I also would like to hear how you feel about 100ZZ. I've just recently moved to it, almost a year, after playing with VZF2 for several years. Now, when I go back to VZF2, especially mid-game, have issues with control shots, like netting, lifts, drops But smashes, lobs, backhands are still a joy... 100ZZ is a good racket for power, plus easy to control shots too...
Got 100zz in 3u and Ryuga 1 in 3u and Ryuga is beast if we talking about smashes. 100zz better control etc, but for power - Ryuga.
