Adjusting racquet specs or technique?

[fpsanti]

Hi there,

I hope this is the right section and that a similar question has not been asked yet.

I'm trying to find my performance ceiling and adjust multiple aspects of my game, one after the other.

My current racquet specs are about 340g static weight, 328SW and a balance of about 32cm.

I've noticed that with a slighter head heavier balance my groundstrokes are very good but I'm struggling to generate head speed on the serve.
If I move the weight towards the hoop, and move a few grams from the head to the handle thus achieving the same specs I get opposite results.
My serve improves dramatically but groundstrokes get worse, especially my 1HBH.

Is it to be expected?
Shall I keep trying to find the perfect tuning (if it exists) or stick to one and work on my technique?

A few additional information about me and my racquet.
4.5 player (best guess), playing in club and tournaments. I like top spin from the baseline and playing on clay, but I don't mind going to the net. I often go (too early) for winners.

My theory on this ... is that if you can have a strong serve with a given set-up, then you should use that and learn to do well with it on the other strokes ...
but if your serve is just never a weapon, then go with what works best for your groundstrokes,
since with weak to avg serve, your groundstrokes will need to carry a big load. Having a big quality serve will greatly lessen the load, but only if that is a realistic option.

This is a game of holding serve IF YOU have a good serve. If not, then it is a game of breaking serve and depending more on good groundstrokes.

If you are not sure which route is best, set up 2 rackets differently so you can try both approaches to your game and see which seems more productive on avg..... If you have a racket set up for serving in the bag, you might find that you can use it to develop a highly effective serve.

Are you implying that there is no ideal setup to maximize all the strokes?
Thanks for your feedback, it makes definitely sense

@socallefty had an interesting posts here, about young players who maximize all strokes with lighter frames:

Anyone Try to Wean One's Self off of Heavy HL Frames

Rotator cuff tear and minor TE rehab back in '98 forced me to get comfortable with heavy, headlight frames. My specs were 360-370g and 12-14pts HL. Played this spec until a terrible car crash around 2017, --then was in rehab til 2020. BTW, longtime S&Ver here. Here I am in 2024, now 60 y/o and...

tt.tennis-warehouse.com

Speaking for myself, my specs are the second ones in my sig, and I maximise ground strokes as per @5263 , in terms of control and power. But the serve isn't too bad with those specs.

These old posts from me are more relevant to your question.

Probably the main factor to consider for serving is to find the right swingweight where you can generate high racquet head speed (RHS). That right range depends on your strength and technique. You have to find the right range where the SW is low enough to serve well, but high enough to provide good stability from the baseline and at the net. It is always a bit of a compromise to find the racquet that you serve the best with and at the same time play the best with from the baseline and at the net.

Spin potential might be something to consider also if you have a high-spin serve for 2nd serves, but less of a factor if you are bombing flat 1st serves.

It’s common that when you have time to set up on strokes and also on serves, players prefer slightly lower SW as they can generate higher racquet head speed (RHS) and hit or serve better. If there is not enough time to set up properly and take full swings on ground strokes as happens on defense or if a player has a bunty swing that is pretty linear, it is common to like higher SW as the extra mass gives depth and power. So, the racquet that a player plays well with is always a compromise between these two requirements - not too high a SW for serves or offensive shots and not too low a SW for playing defense.

Different racquet specs deliver different pros and cons. There is no one good panacea for every player’s serve. Generally a whippy, low SW racquet can help generate more RHS if that’s what you struggle with and it is usually good for generating spin on 2nd serves. A heavier racquet with higher SW might have the extra mass to deliver some good punch on 1st serves. So, usually there is a compromise of racquet specs that might hit the sweet spot between 1st and 2nd serves for each player. Similarly, the best serving racquet might not be the best one for groundstrokes and volleys - that is why there are no universal truths about which racquet is best for particular shots.

But since every player‘s strength, height/arm length, racquet history and technique including ability to generate RHS are different, what one player considers whippy may not be the same for another player and what one player considers heavy might not be for another player. You wouldn’t expect a 7 footer vs a 5 footer, a scrawny 130 lb player vs a muscled 200 lb player, a 7.0 pro vs a 3.5 rec hack, a player who grew up with wood vs a young player who grew up in the poly era, a physically weaker 70-year old vs a young man in his physical prime etc. to all agree on the same definitions of what raquet specs are optimal for them, what is whippy, heavy, large sweet spot, what is precise etc. It is the same with important specs like beam width, head size, static weight, SW, stiffness etc. - what each player comsiders optimal is uniquely different.

There for sharing the old posts, very interesting.

Assuming I've got two different racquets with identical specs, except for twist weight.
How the lower resp. higher TW would affect those strokes, if anything?

 

[jimmy8]

Try a blade v9 16x19. It's so stable and so maneuverable at 307g unstrung, unmodified.

Maybe also try shift 99 300. Also very stable and very maneuverable at 300g unstrung and unmodified. Also great spin.

Do a demo. If you like them, buy a used one for cheap.

 

[5263]

Are you implying that there is no ideal setup to maximize all the strokes?

No, not at all. It is probably fairly common for players to like a racket for both serves and ground strokes... especially if they use or understand the 4 aspects that are common to all tennis strokes. I think the bigger issue would be groundstrokes vs volleys instead of serves.

I was just addressing things for someone who couldn't bring the 2 together and how do decide which is the better route in that case.

 

[FuzzyYellowBalls]

I'd guess technique 97%, racket 3%, when it comes to actual match wins and losses.

Assuming at 4.5 ish you have a brain and aren't buying a racket from Walmart and know what SW you like. Seems you do.

 

[5263]

These old posts from me are more relevant to your question.

Imo the main key to racket specs is the level of player you normally encounter... 295- 315 grams is fine for the pace of 3.5 and light 4.0, but moving up to 4.5 to 5.5 avg pace I think more like 330-350g is better.

 

[5263]

Not too sure about that, as we have all seen Pros go into a slump when changing rackets even though they normally try to have very similar specs. And this could actually be worse for mid level players who have tuned their games to a given swing wt.

Now for beginners, I don't think it matters too much, although I like to start them on the heavy side to encourage them to learn to "Lag to Drag" the racket.

Hopefully Pros aren't reading my comments on TTW forums for tips , hi Nadal! I'm a big fan, in case you are reading this.

 

[ngoster]

If all else fails, it could just be the racket.

I can't speak for the 4.5 level but as an older 4.0 player, my serves don't generate as many free points as when I was younger so I have to rely more on winning points off the ground. Sometimes, they are good enough to allow me a slight advantage to begin the ground game but most just get the points started. I feel the same way with opponents. Approaching the game this way, I feel that it's more important to develop a good ground game, therefore, I would favor the racket for the ground vs the serves.

I have this with my current two racquets by about 2 TW points and there’s virtually no difference besides obviously hitting off center, especially on serve returns.

For me, the higher TW racquet is a little more “locked into” a certain racquet face angle on my groundstrokes but it’s such a minor thing that doesnt bother me.

 

[5263]

Hopefully Pros aren't reading my comments on TTW forums for tips , hi Nadal! I'm a big fan, in case you are reading this.

so you didn't get the point that is likely even worse for mid level players (4.5-5.5)?

 

[FuzzyYellowBalls]

so you didn't get the point that is likely even worse for mid level players (4.5-5.5)?

I guess not, I was suggesting technique is around 97ish % and racket 3% of match results, I don't know what worse is, or what you are suggesting, more racket % or well, I guess more racket % since I have it around 3?

I have a heavier racquet with higher SW, that swings easier then lighter sticks with lower SW, most probably due to the TW.

I second @5263 on this one, as I think the equipment matter more, or can affect those players more...

A lot more though? My assumption is someone buys a racket form a tennis store, whatever the seller suggests, let's say they walk into Tennis Spin shop and get a "good" racket, not a generic retail store. At that point when it comes to matches won or lost, I don't think the particular racket is remotely as significant as technique. We can play with the percentage if you have another suggestion like 80/20, but still technique dominates, when it comes to winning a real match.

If you randomly consider 2 players of wide range of skill level - yes, for sure. Yet in real life you normally compete with similar level players. And here technique proficiency is usually quite close. More to it, the higher the level, the closer other aspects, like fitness and mental strength, are.

The point is, you are not loosing neither gaining your technique between games. But if a strong player in the middle of tough match against a peer gets his strings snapped and forced to play with inappropriate replacement stick, he’s likely toast. Just like getting injured.

Or if he picks a racquet that doesn't work well for him, in general, or needs an adjustment period.

Sure, that's a little different than what I am trying to say, to reframe it into what the op asks, is it the racket or technique, I say mostly it's technique, OP asks specifically performance ceiling which racket from a good manufacturer, Yonex, Wilson, Head, Babolat, is really going to reveal a significant match winning new performance ceiling for a rec player and if so, is that a 1% boost, a new 20% boost in a play level, and which strokes at which point during the match is that performance ceiling/boost going to show up, every hit of the ball? That's why I lean on technique being so much more important.

Even in your example, although not that relevant, a player will have a good replacement racket if his strings break .

 

[FuzzyYellowBalls]

Or if he picks a racquet that doesn't work well for him, in general, or needs an adjustment period.

I could just be ignorant to all this I guess. I've gotten demos from TW and used them in tournaments with sometimes not great strings, alternating rackets each game during a match, sometimes 3 different ones and been fine, with hardly any adjustment period. I've also seen opponents feverishly switch rackets trying to turn thigs around and it doesn't help at all. I'm just a mere mortal non pro so I assume everyone can navigate like this, I mean you've seen my poor technique, but I am not missing shots because of the rackets . All the rackets are generally "normal" good rackets with HL between 4 and 7, sw 311-330, so no game killing difference in my mind, who wins the points doesn't change with the racket from what I have experienced.

I think we're all agreeing on the same thing. If technique is poor then it doesn't really matter what you use. "Good" equipment can only get you so far because you're limited by your technique vs what your equipment can do. Inversely, the better your technique is, equipment becomes more of a factor as it's now a tool to maximize your abilities.

Poly strings are a good example. In order for them to do what they're designed to do, you need to be able to generated enough RHS to get snap back. If your technique limits you to having a slow pancake swing, the strings won't do anything for you.

 

[FuzzyYellowBalls]

I kind of think the opposite, while I did say my technique isn't "good" I guess it's relative, I'm not missing shots or losing matches just trying to improve on bad habits, still performing well with any racket, even had to borrow ancient purple hyper hammer from the 90's recently in a match and no problem, just adjust a little and it worked well enough to win . I can squeeze good performance out of almost any racket because reliable, if not perfect technique is drilled into me I'm pretty sure any of my teammates or hitting buddies could too, maybe not really enjoy it, but they wouldn't lose enough ability to win a match if they had to swap an Ezone 98 for a Vcore 98 or a Pure Aero, or a Percept or a Strike etc. or a Speed Pro, they'd just have a preference of one over the other.

That's why I opined the technique is so much more important than racket, unless Nadal wants to chime in...

because the better your technique is, equipment becomes more of a factor astronomically when discussion pro level players, that I agree on.

Yeah, but when you switched rackets and won, what was the competition like? Was there any pressure to perform? I can switch rackets during rally sessions or when playing against easy opponents, but I'm not sure my performance would be the same if I was under pressure against better opponents.

 

[FuzzyYellowBalls]

Good question, I didn't feel too much pressure since I was goofin around anyway and won, but more to your point, I don't think I would lose a match because of that, I would just win and lose the matches I would otherwise win and lose with a racket I've used for a year. Maybe if there was an exact clone of myself it would impact the win or loss, but I really don't think, for me, it would cause me to win or lose. I don't think that is everyone, but I also don't think my feeling is just me, there are others who would not lose the ability to win by switching rackets , so the other side of that is I don't think a perfect racket ( and no one really chooses a perfect one, I doubt that, we all just guess or go crazy trying them all) can make most rec players overperform their technique.

 

[Bagumbawalla]

If your groundstrokes are improved.......then just work on your serve.......,easily done....... try using weights to beef up your
shoulder strength. I had a similar situation when changing to a heavier racket.

My groundstroke were killing but my serve was lagging- the same serve, but sort of in slow motion. At first I just used my ball hopper as a weight
while duplicating the serving motion- then I went to actual weights, then throwing baseballs and footballs. Anyway, eventually I beefed up my
shoulder strength and am happy with the result.

 

[Deleted member 775108]

I've noticed that with a slighter head heavier balance my groundstrokes are very good but I'm struggling to generate head speed on the serve.
If I move the weight towards the hoop, and move a few grams from the head to the handle thus achieving the same specs I get opposite results.
My serve improves dramatically but groundstrokes get worse, especially my 1HBH.

Is it to be expected?
Shall I keep trying to find the perfect tuning (if it exists) or stick to one and work on my technique?

If in doubt do the middle path - split the two setups exactly - trust that it will work - calm your mind - keep playing.

I'd say the problem is in how this situation is framed since both technique and racket setup are very key to getting the ball where you want it, at the speed you intend to send it. So from my position, this is a great example of "Dual Objectives", where both technique and racket setup are very key to consistent execution and even help each other more than most realize.

Imo technique problems are a far more obvious problem whereas the racket setup is much more insidious. For years my forehand and serve velocity were greatly inhibited due to me being overly humble about my skills vs the role of my racket setup. I finally realized that if I could hit quite well and precise at lower power swings, maybe it was my racket setup that was failing me as I increased the swing speed.

1st I tightened up my string tension and it helped. THen I went to poly and it was like a new world of control, meaning the ball went where I intended instead of wildly changing trajectories based on swing speeds....but I did lose some velocity output vs the swing speed input with 16g poly. So I went to 18g and most of the velocity returned. I went to Big Ace Micro which is 19g+ (much like Sampras) and could get excellent velocity for the input power, but lost a touch of control on launch angles at times like with syn gut.... so increased the tension slightly and boom, that was great! Then with better control and velocity, I started adding some lead tape, but kept the same stick balance, which also added some power without losing control.

So my point is that until you get a good setup, you don't really know what you are capable of.... and using a heavier racket can even help you to develop certain qualities to your technique, like learning to "Lag to Drag" the racket out of the backswing.

Good points, that's why I kind of repeated the context of walking into tennis spin shop and getting a modern off the shelf new racket, that's going to have poly put in it for sure by the shop owner after some conversations. I kind of assume poly in the racket discussion as much as I would assume someone wearing tennis shoes for tennis and not thin running shoes for tennis.

Then, if poly doesn't help a player for whatever reason, the racket is still not dominating technique when it comes to wins and losses.

And yes, perhaps no one really knows what they are capable of, but my context is does that win more matches? Like I believe a heavier racket for fictional player X might allow him to hit 2 or 3 mph faster on serve, but does that directly translate into winning a match he wasn't winning with another racket? I doubt that happens at a significant rate.

Sounds like you have fine tuned your setup though, which must be a peaceful feeling to not worry about it anymore.

 

[Dragy]

but does that directly translate into winning a match he wasn't winning with another racket?

It’s the other way around, is it possible to loose a close match by switching to less-than-optimal racquet? Absolutely.

Switching to better racquet may make you a better player, but you obviously need some adjustment period to capitalize. Although @travlerajm would possibly argue proper tweaks give immediate result

For you personally @FuzzyYellowBalls — go play higher competition where your lazy second serve is no longer better than decent serve.

And once there, and playing close matches, commit to one good racquet for couple of month, and see if your results improve over goofing around with test sticks.

[socallefty]

The eternal dilemma for a good player is whether you have the time to keep tweaking your equipment to make it more optimal while you have to keep winning matches or if you want to lock down your equipment (racquet/stringjob) and forget about equipment variations to your game while playing matches. Your game/shots will be influenced by the racquet/strings you used to develop your game and your optimal equipment will depend on the game you already have developed - they are intertwined. If you are still at a beginner stage where you haven’t stabilized your fundamentals, better to stick with the same racquet and strings for a few years before you start tweaking.

You are going to lose some matches that you might have won during the process of experimenting with racquets/stringjobs as it is hard to feel confident to execute well at stressful moments of a match with new equipment or to stop wondering when losing if you would be doing better with your usual equipment. With the pros who can’t afford losing streaks, they will tweak equipment during some offseasons or if they are looking for a new racquet sponsorship contract - they are not going to change racquets every time their sponsor makes some tweaks to the model they play with. Many of them end up playing with the same racquet and stringjob (tension changes notwithstanding) they used in their junior days for their entire pro career because they are so conservative about not wanting changes to what they are used to.

With rec players, there is low hanging fruit to improve with technique/footwork improvement, mental strength, strategic improvement and with equipment optimization. The lower the level, the more there is avenue for quick improvement by focusing on technique, footwork and mental/strategy changes - so, it might be good to keep equipment stable while you are focusing on that as long as you are playing with a bestselling racquet and bestselling poly plus you know the rules of poly usage. Otherwise you might go on a rollercoaster of equipment tweaking while your ceiling will remain low with limited fundamentals in technique, footwork and mental strength/strategy. The problem is that those who lack fundamentals in tennis also haven’t played enough under proper mentoring to know what kind of racquet specs or string jobs might be appropriate for the game they already have.

If they try every racquet and string out there along with customization and hybrid ideas they get from this forum, they might spend their whole life tweaking equipment while never developing the fundamentals of tennis enough. Also a fundamental point that many rec players don’t get that a racquet with one stringjob is just capturing a sliver of its large performance range and you can adjust its power/control,spin, comfort, feel over a huge range by tweaking strings, gauges and tensions. A racquet strung with 18g gut at 45lbs is going to play/feel totally different than when strung with 15g stiff poly at 60 lbs - now if you reverse the tensions, it will feel like a third and fourth racquet. It is more important to experiment with strings on one racquet and understand how string stiffness/material, gauges, tensions change racquet performance before exploring a wide range of demo racquets each strung with one stringjob of uncertain tension/age.

The more years you have played at an advanced level and the more you know what your racquet/stringing preferences are, you might want to do some experimentation particularly with strings (change strings, gauges, tensions, try hybrids) to optimize your game further. Unlikely that you need to worry about changing your racquet specs much as you will gravitate to racquet specs (especially weight, SW, beam width, head size) that are similar to what you used as a junior while developing your game. You probably should try the new setup in practice first and see if you get some confidence with it before trying it out in matches.

Every 5 years, my racquet model gets discontinued and I use it as a time to demo some new racquet models with similar specs. I might also try some newly released strings and tweak some tensions/gauges at that time along with my usual stringjob. Then I pick a new racquet with a new stringjob and lock it down for the next 4/5 years during which I don’t want to think of my equipment at all. This is because I am not interested in losing any matches while tweaking equipment - I treat every match I play the same way. They are all meaningless in the bigger picture as it is rec tennis, but for me on every single day I want to try my best and so I want to give myself the best chance to win every match every day. So, I don’t like to tweak equipment and try a new setup during matches unless I have developed full confidence from using it multiple practice sessions. Other rec players might have more stomach to lose some matches while tweaking their equipment.
