Tourna Power Cap

This works only for size #2 and under, anything size #3 and above and the cap moves around too much. I tested this under leather and synthetic grips.

I add this to my Yonex racket and then put overgrip over it. I like it because it adds comfort and a little weight to the handle. Easy to apply.

certainly helps you slide down the pallet and in effect not grip it too hard when serving, thereby making it easier to serve big or get better spin/kick. Note however that if you already use a head light racquet, adding this very light piece of silicone still will impact the balance point of the racquet quite noticeably. Then you will need to add tape and change your set-up quite a bit. On the other hand, if you're looking to make a neutral/head heavy racquet more head light, adding this piece would be an ideal way to do so.

I really like this!

Similarly I have a Yonex racquet and was looking for a flared butt cap. This is also a simple way to slightly extend the length of your racquet which in turn adds swingweight.
