Stiff poly with higher launch angle than Tour Bite

#1
I've recently switched racquets to the SW104 and found that my old go-to strings haven't worked quite as I wanted. I've been trying various strings and gauges, and I significantly prefer the stiffer poly strings. I had a couple of sets of Tour Bite 1.30 and have even found an ideal tension, only the launch angle is a bit lower than I would prefer.

I've ordered Cyclone, Solstice Power, Revolve Spin, and Hyper-G, all in 1.30 diameter. Any other recommendations for shaped poly strings that have roughly the same stiffness as Tour Bite, that would give me a bit of a higher launch angle?

Thanks.

trav, our club closed at 4 p.m. to let staff get home, and will open again tomorrow at noon. Also, I'm hoping that my wife and I will be able to make our flights out of town this coming Wednesday - we've got a Costa Rica getaway planned. Can you make it to Kirkland any time next Monday or Tuesday? I'll grab a court for us! Or would you rather play at your courts?

Can't make sandpoint today! I'm supposedly playing at 4 p.m. tomorrow with my son if our Club is open, so how about Sunday?

I'd love to get your opinion on my current racquets, and to pick your brain on stuff like MGR/I!

Let's plan on it! At Sandpoint? I've never been there so I'm looking forward to it. Let's chat Sunday morning.

Any thoughts on strings and launch angle? Is this something you think I can adjust by varying the tensions in the mains and crosses? Would 50 mains and 44 crosses give me a noticeably higher launch angle than 48 mains and 46 crosses?

Cyclone gives a higher launch angle than TB and HyperG. I compared them on the same frames with the same tensions. I tried 19g though.

Ok. We'll see what the roads look like by then.
Any thoughts on strings and launch angle?
Yes. This is something I've experimented with extensively.
Is this something you think I can adjust by varying the tensions in the mains and crosses?
Yes. The bigger the differential (i.e., the difference between the tighter mains and looser crosses), the higher the launch angle sensitivity to the steepness of your swingpath. So an uppercut swing would produce a higher launch angle. I don't see an increased launch angle per se as a benefit (on the contrary, I consider it quite undesirable, especially due to the higher sensitivity of your launch angle to both the rpm and and the velocity of your opponent's incoming shot, factors you have no control over).

So if an extreme differential increases launch angle, and I consider high launch angle to be a bad thing, then why would I ever recommend that someone use an extreme differential? It's because there are multiplel reasons why a high differential can help give you something not possible without it:

1. Increasing the differential (and compensating for the higher launch angle and increased mainstring deflection freedom by stringing tighter overall to maintain good control) gives you what I call the ESP effect (i.e., it can preserve much of the launch angle control benefit of a tight stringbed with the added spin potential of a looser stringbed). It sort of lets you have your cake and eat it too.

2. With full poly, a bigger differential will reduce denting of the crosses, which will increase comfort coniderably.

3. Due to the reduced denting of crosses, it will greatly extend the playable lifespan of your full poly bed before it "dies."

Would 50 mains and 44 crosses give me a noticeably higher launch angle than 48 mains and 46 crosses?
I think the difference would be perceptible, but generally not that significant. With the large head size and rounded head shape of the SW104, the benefits of an extreme differential that I mentioned above are largely negated because the hoop geometry is not stiff enough to resist squashing, unlike a typical 95si frame, for example.

trav, I pulled out some of my previous racquets and they all are more oval in shape than the SW104, and despite being larger in stringbed area were all 16X19. I think that might be why, for the first time I can remember, that I'm having issues with getting my preferred launch angle. Your threads and discussions about ESP are interesting, but again something I can't take advantage of to the degree that you have been able to, and made more difficult in any case by the 18X19 stringbed.

I kind of wish I had been more aware of the differences that would have been caused by head shape and string density before choosing the SW104. In the past, I had always (accidentally) chosen racquets that were close enough that I could get comfortable with a slight manipulation of strings or string tension. I do get high launch angles with shaped poly strings so I'm inclined to stay with them on the SW104, which doesn't fully offset that I get more preferable stringbed response with a thicker, stiffer string that lowers launch angle.

Side benefit - in the course of looking at my old racquets, I found some of my really old racquets that I had stashed away after I stopped using them. Most intrigued to find the Head Graphite Edge that I used probably 30 years ago. I'll bring it along for you to try - it's really old school with a leather grip and strung with TNT Fat Core, so the string job isn't probably more than ten years old. 360 grams and the grommets are not cracked. No complaints!

Tomorrow might be kind of iffy for me to get a hit in with you. I've got a honey-do list so long it makes my head spin, and I'm out of town starting Wednesday. Let's play it by ear but I'd love to hit if I could. I had a court time today but our Club never opened due to snow.

Now also on my list of strings to try are RPM Blast and Lux Alu Soft and M4.

trav, thanks for the link. The launch angle issue seems to be one where personal preference plays a big part in what would be desirable for any particular player. In my case, I greatly prefer launch angle differences even though I am often subject to issues caused by the spin of the incoming ball. I play against a couple of people who can hit really heavy underspin and it is hard for me to effectively volley against them, especially on the forehand side, because I don't always get the angle correct to compensate for the amount of spin I believe the shot has. I seem to put these into the tape more than anything, and then the next time I overcompensate and float the volley long. Both guys, both righties, seem to put more underspin when going down the line than crosscourt and that compounds the issue against my less reliable forehand volley.

The flip side, though, is that high launch angles seem self-compensating with my strokes. If I swing at a groundstroke and it happens to bounce higher than I am expecting, I usually won't time it perfectly and so there's less ballspeed off my racquet, but a higher launch angle means that my more upward stroke at it gets more air under the shot, and it has greater depth that way. Conversely, if the ball bounces a little lower or faster than I am expecting, I'll tend to catch it with a slightly closed face and a high launch angle can help the ball just skim over the net instead of hitting it.

Same with an extremely extended backhand slice, one where I am almost 180 degrees turned around to get maximum reach. In that position, it's impossible for me to do anything but hit an underspin and lead with the bottom of the racquet face, and having the strings grab the ball makes it a less floaty, deeper shot. A grippy stringbed, sensitive to incoming spin, also has helped me with drop volleys. It was almost a relevation the first time I tried a shaped poly and found that hitting a drop volley off a heavy underspin shot was so much easier than with the round poly that I was using before that.

In any case, it's not launch angle why I lose to the same guys in age group matches. I play an unsustainable style for someone in my late 50's because I'm still trying to play like a modern young player. That's effective to a certain level, but the top guys in the 55's all train juniors so all of a sudden my game is something they see all the time, and they win me out by putting balls in difficult spots and waiting until I miss. Or waiting until we get to 3-3 and then I get broken because I try to do something special in my next service game and make an extra error that loses me my serve.

Interesting to note that none of the top age groupers in the 55's hit with anything more than moderate pace and moderate spin. There's a lesson there for me, only I'm too stubborn to take it and believe in it.

@travlerajm , @Injured Again , are you guys in PNW? Sandpoint and Snowmaggedon are only used around here.
I got in a hitting session with my son before the snow started again. Club closed right after that.
Yep. I'm a member of Central Park in Kirkland. We got in a very early dinner with my mother-in-law and then I got out for a very light hit with my son (except he's 25) right before our Club closed. Got about three inches of snow tonight. In any case, we should see who else is from around here and arrange a day to get together to put faces and names together.

I did pull out the Graphite Edge that I used back in the '80's and hit about a dozen balls with it. Certainly has that plush, pocketing, wood feel to it. Power is actually not bad either, with the ten-plus year old synthetic gut strings that were long past their use-by date. The leather grip was beyond done and I didn't want to boomerang the thing into the next court so it went back into the bag.

I pulled out the SW104 strung with 1.25 black Cyclone and think I may be gravitating towards it again, despite it being a bit more powerful than I prefer. The launch angle is definitely higher if only by a little bit, and better suits my swing style. This has been the most frustrating part of this racquet switch. I never had this many changes of mind, or doubt, ever before.

I dont experience lower launch angles with Tourbite 1.20, however it loses tensions pretty fast which is a good thing with this stiff string. Maybe you could try hybriding with a smooth slippery poly like Outlast?

Earlier on, I tried a hybrid with Diadem Solstice Power 1.30 and SPPP 1.23. The Solstice Power was my go-to string previously, but I used a 1.35 gauge in a 16X19 110 square inch racquet. The 1.30 was a leftover from a previous reel and the 1.35 is just too large to work well in the 18X19 and added four grams with a full bed versus a 1.25 full bed. The 1.23 SPPP crosses helped with the weight and in total it was just one gram heavier when paired with the 1.30 Solstice Power.

I don't think I got the tension right. It just felt too springy any time I swung hard, though I do remember a good and high launch angle when I swung more slowly. I guess the SPPP 1.23 was just not firm enough and I should have used a higher tension. I've never used hybrid stringbeds so I don't have good experience in this area. I have several questions.

1. Is the Outlast and SPPP that much different in their stiffness?

2. When hybriding with different gauge strings, is there a general guideline as to tension differentials, or is it only based on the actual string stiffness?

3. What is the consensus with significantly gauge differences? I have a half reel of Solstice Power 1.35 and have 1.23 or 1.18 SPPP, and 1.12 Big Banger Ace. Not advisable?

Thanks.

I find that what I guess something will feel like doesn’t always match what happens when I try the actual experiment. I used to think that using a thinner cross would always be better, but every time I use a thicker cross in a hybrid, it plays surprisingly nice.

trav, I appreciate the feedback, but unfortunately it kind of frustrates me more. Like you say, sometimes what seems obvious just doesn't work that way, making it something I can only find out by trying. There are just so many variables and I don't know why I seem to be having such a difficult time nailing down the response I want. I played this morning against a guy who hits the ball very hard and very flat, and we used faster balls than I used with my son. The Cyclone was just too powerful or needed a bit of extra tension, so again I felt the most comfortable using the Tour Bite.

I guess I should just look at the process as one of being fun and allowing me to try things I wouldn't otherwise do if I had pretty quickly found my ideal stringbed response, but I'm tired of second guessing myself and league season is starting up soon. There's still an adjustment period with the racquet that I need to get through - I'm still tending to jam myself up when I have to run hard sideways to the ball, but I wouldn't give up that extra inch of length for all the other benefits. I just want this to be over with so I can work on my game rather than fiddling with my racquet, cause my game definitely needs a lot of work.

I guess you're right. Even when I found my desired string, I still tested others just to make sure I wasn't missing out on that magic string that would all of a sudden help me reach more balls or hit shots I only see on TV. Only thing is I had a go-to setup that I now don't, and that feels unsettling.

1. In a hybrid i find outlast stiffer and more slippery.
2. I think you should try thinner cross than mains better than the other way around. There is no rule for tension differences, but if too much i would be afraid of frame distortion.
