Had a 3 hour singles match yesterday with DNA. Then I hit with the Gamma Pro and Ashaway Dynamite this morning for about 5 minutes each. The Dyamite felt softer today. After 1 hour of hitting, I played the same guy I did yesterday 2 sets of singles and then we played 2 sets of dubs. The good news is that DNA is one of the best multis I've tried. The better news is that Gamma Pro and Dynamite felt even better to me in the brief time I used both.
