Launch angle too high. Strings, tension, racket lead position or string technique to lower ball flight

2ndServe

I'm playing with a Wilson sw104 extended racket, really like the racket but the launch angle is really high imo as with most extended rackets.

I'm playing kevlar in the mains (tighter mains helps lower the flight but I prefer 40's tension for my arm), softer poly in the cross helps lower the flight also. should I try more lead tape near the throat or 6 oclock area? Should I try like 60's main and 35 lbs cross? Just looking for some ideas, thanks

Can you try lowering the cross tension? I'm experimenting with a poly/syn gut hybrid and the difference in launch angle going from 50/50 to 50/48 then 50/46 has been dramatic, I think especially because the syn gut is so much softer than the poly.

Are your mains staying splayed out. (No snapback)? Thats my guess for the high launch from the Kevlar. Try to go to 55 lbs. Not any less comfortable ime.

Also, monogut ZX is just as slippery as poly, about the same power level, but more comfortable.

Kevlar is not a high launch angle string. I'd suspect the poly as the culprit or else your technique. Some polys are inconsistent in their response in my experience. I usually like to play with muted polys as I don't like hot spots on the string bed or any kind of inconsistency other than those I may or may not on occasion produce myself. :)

Kevlar is high launch if strung too low. (If a low to high swing)

Kevlar is interesting. There is a bit of variation depending on which particular kevlar you are using too. Since kevlar doesn't stretch hardly at all, stringing it at 60 vs 40 is a very small difference in performance usually. A braided kevlar will have a bit more stretch due to the construction, so you might get a slightly higher launch angle with it once it relaxes in the frame.

So there are a lot of factors. It might help if the OP would post the specific strings and tensions.

the video review of this racquet said they strung it with lux.4g @52lbs and most found too much power at times !?!?
based on that, I would try FB-poly at 55mains /56crosses, no lead!!,
this is a 18/19 pattern 104",, I would try increasing the crosses a bit, 1-2lbs from what ever the mains are..

mains ashaway kevlar + at 40 lbs
cross pros pro blackout at 35 lbs


I have another at 48 lbs main and 36 lbs cross, haven't tried it out yet, same strings.

There cant be such thing as too high angle, too low is much worse, lol .
Maybe you r too late with your swings because of high swingweight racquet and you ll compensate by not getting your weight into the shot? Anyway i never understood the need for kevlar. Why not fullbed multi or poly?

I disagree a low launch angle gives more consistency and more confidence to swing out, also more time the ball is in the air (higher) the easier it is for your opponent.
This is not true.
If during normal ralley you hit too low, chances increase you either net it or it has not enough depth. Now that makes it much easier for your opponent. If you want to hit out, you simply apply more topspin, and you never hit too long. Have you observed Thiem?
Also besides his footwork, the topspin and height of Nadals groundstrokes makes him so consistent and nobody calls his shots too easy for his opponents, lol.

Per TWU http://twu.tennis-warehouse.com/learning_center/trajectory_info.php

Tennis Warehouse U said:
Launch angle is measured against a horizontal line to the court. It is positive if the angle is above the line and negative if below. All other shot parameters remaining equal, the racquet with the higher power potential will hit the ball faster and at a lower launch angle. Less powerful racquets will launch at a higher angle. It is possible the two effects will cancel and the ball would land in the same spot. It is also possible that one effect will be greater than the other — for example the less powerful racquet (lower launch speed) launching at a higher angle and actually hitting farther. That's why it is sometimes confusing when talking about power. But power refers to speed not distance. Fortunately, most of the time, the more powerful racquet will hit both faster and farther, though not necessarily farther.
So anything that will make the racket more powerful like extending the racket, adding weight, lowering tension, or using a softer string will give you a higher launch angle. The only thing you have going for you is you are using a lower power string (kevlar.)
 
The term ‘high launch angle’ is shorthand for ‘high launch angle sensitivity to the impact parameters.’ Impact parameters include things like incoming ball velocity and incoming ball rpm, which you have no control over. So high launch angle is very bad for control, and low launch angle is very good for control. The following will help give lower launch angle:
1. Tighter tension.
2. Stiffer strings.
3. Stickier surface crosses.
4. Stringing crosses tighter than mains.
5. Anything that limits freedom for mains to move.
 
why would increasing cross tension say 5lbs lower the flight more than increasing the main tension by 5lbs?
When mains are tighter than crosses, it allows more freedom for main string movement. This increases spin, but at a cost of higher launch angle unless you compensate by stringing much tighter overall.

The launch angle is higher because when the mains are pushed downward, it creates a big gap between two of the mains at the top edge of the contact area. This gap is a local soft spot in the stringbed. The ball dents (or ‘pockets’) into that soft spot. Since the denting is at the top edge of the contact area, the denting increases the angle of the stringbed in the area of ball contact. So the ball launches at a higher angle.

which setup will have a higher launch angle, 50/40 or 40/50? what about 50/40 or 40/45? or even 40/50 vs. 40/40? i guess my question is, what is the effect of main string tension as opposed to the effect of the differential between mains and crosses?

Pretty much the same thing TWU said. They said the more power, the greater the launch angle. Increasing tension on the string (mains, crosses, or both) lowers power and the launch angle. Maintaining tension constant and switching to a stiffer string lowers power and launch angle. But when the mains are tighter than the crosses it does not necessarily increase launch angle. I can have the main tension higher than the crosses by raising main tension or lowering cross tension.

When I string full poly at 80/50, it does not feel like 65 lbs. it feels like 55 lbs because the ball pockets into the stringbed more, due to extra freedom for in-plane mainstring movement.

50/40 would always have much higher launch angle than 40/50, and in most cases also more spin.

The other comparisons you asked are closer to call and depend on the details of the string types.

With those ridiciously high poly tensions you could use a frying pan as well, lol. Maybe you dont feel it because the tension difference with the crosses deforms your racquet too.
Furthermore attempting to reduce string snapback may reduce sensitivity to incoming ball spin, it also greatly reduces your own spinpotential greatly. Maybe you dont care because you r an oldskool flathitter?
Anyway Nadal, Fed, and Nole are highly successfull with their optimized string snapback setup, so ofcourse we are no topplayers like them, it cant hurt to understand why they are so successfull hitting topspin and slice.
 
50/40 would always have much higher launch angle than 40/50, and in most cases also more spin.n
This has been my experience. There is a player in his 60s I string for who has the flattest fh you will ever see. His swing path is horizontal with barely any low to high movement in his racquet head. 40% of his shots would drill the net cord, until I got him to try a 6 pound drop in the crosses. The increased launch angle immediately elevated his game and confidence without having to modify his stroke, footwork and timing.

Try Pro Supex Synthetic Gut Spiral Flex 16g $3.50 (available at ************** online) for mains and Prince Warrior Response 16G $5.00 crosses (available at Tennis Warehouse online). String them both at 50 pounds (it's the low end of your racquets recommended tension). You'll get comfort, spin, and enough control to keep the ball in the court, and 2 racquets worth of string for under $10, plus shipping. Don't let others knock it before you try it.
