no, Anna does use gosen grips and dampeners
I have search for these products in the past but with no luck. But recently I went to my local pro shot and i saw that they had some gosen grips.
I belive Anna either uses the OG soft grips or the Hy grips. Her grips has like little holes. i have seen picture on her on the cover of thoes grips on the net. As for the dampener, she is the only person that i have ever since using it, not even players gosen endorses. I wonder how the 2 products are different from each other and if Anna swich because of a contract deal which made her show that she uses gosen product.
here is the tennis to my local pro shot- ************.com . you can email the owner to see if he know anything. i must warn you its not cheap since its the nearest shop to me and the next one closest to me with about 20 minutes away.
remember to inform if you have any luck.
