Racquet stability ?

Is stability of a racquet all about twist weight, power and plow index at 3 and 9 ?

So to make a frame more stable, adding lead to 3 and 9 o'clock will suffice ? or is there any other thing I am missing ?

There's loads of threads. You will get some added stability even if you add the lead at 12 since it increases SW, but yes, you get the most plow and stability with lead at 3/9. You can also mix it up a bit with some lead at 12 (or 10/2) to raise the sweetspot and increase SW with smaller amounts of lead - adds power too. Then, add some at 3/9 to increase torsional stability and plow. I have lead at 9, 10:30, 12, 1:30 and 3 and like it a lot - very stable, more power and plow.

Search for the polarization vs depolarization on this board - it goes into great depth about the pros/cons of lead location.

I actually know quite a bit about the subject. My main question is: can the "feeling" of stability be created entirely by adding lead to 3 and 9 o'clock ?

Adding weight to 12 will increase the swing weight too much. For my practical purpose I want to get stability but at the same time increasing the swing weight the least.

I played around with TW customization tool and indeed adding lead to 3 and 9 will increase twist weight and plow index at 3 and 9 the most. The last time I added 6g at 3 and 9 but it became too much of swingweight. Then I tried to add 3g at 12 but again it did not feel good. So Now I am trying only 3 g at 3 and 9.

Hey bud, I added almost an oz of lead to my PSC6.1 @ 3/9 and it was fantastic. Had a strange feel as I was basically just playing with lead, and there was SO much flex in the sweet spot it was fantastic.

The stick was 14.0oz when it was all said and done, and it played great. Just too much for competitive play against higher level opponents.

If you have any specific questions let me know, I've played with tons of lead! :)

As for the stability, lets just say I was volleying overheads out of the air without any real harshness on my arm. ;)

Hearing people talk about adding an ounce is mystifying to me. I put 2 grams (4 lead power strips) on 12,6,3,and 9 respectively and the difference was significant. When I tried to double that, I lost significant racket head speed. I cant even imagine what adding an ounce would do.

Thanks Fuji. I am playing around with my Vcore 100s and BLX Pro Open. In stock form, the 100s is better at creating spin and in forehand side it is easy to swing and keep the ball in. However, the Pro open is better for my one hand back hand. Pro open is also better at returning since it is more stable and not twisting if I don't hit the sweetspot.

I checked the TW database and the twistweights of Pro Open and the 100s are 14.48 and 12.8 respectively. So my goal is to re-create the stability of Pro Open in the 100s without increasing much swingweight. I am not that big and my fitness is dubious, so the lighter the better :) on the other hand my arm hurt with lighter frame so in that area, the heavier the better.

Wow, I suppose the PSC 6.1 is already quite stable. With 40g more at 3, 9 it would be like the hammer :) no doubt, heavier is better if you can swing it for the whole match. I played a close 3 set game the other day. Passing 2 hour mark, my feet did not move and I felt a certain numbness in the wrist. At that point, my forehand became a certain slow pushing arch instead of swing. It seems like my one-hand back hand is the last to break down under fatigue

Welcome bud!

Adding that much weight isn't too bad, as it weighs the same as what my KPS88's are at, and I use them pretty frequently. The huge difference was balance. The PSC6.1 was only 5 points HL, while my KPS88's are at close to 10 points HL.

My ground game and volleys were fine, it was just getting the RHS on the serve late game which was the problem. I could hit bombs on my first serves, but to hit a decent kick serve was brutal! LOL!
