I bought some more dampeners and added my thoughts and the weights to the original thread .....
Babolat Custom II (square)
It is an improvement over the circular ones they used to sell as this square one stays in better. It’s soft rubber, medium weight, expensive but good.
Looks cool and the rubber is soft but still harder than most other damps I’ve tested so not recommended.
Gamma TNT Core (2.5")
Only seeing it online I was prejudiced against this from the start figuring the name is a joke. When I got it in on the strings I liked its soft rubber as it is the softest of all I’ve ever tested. It applies to the racquet nicely and looks good. Yea Gamma.
Head Smartsorb (4.25")
I swap back and forth with this and the generic TW damp. The Head is flatter, shorter and has very short “fingers” to grip the strings. This one compares much to the TW generic damp and, between the two, I still like the TW damp slightly better.
