Well, I *thought* I had my serving problems solved with the RDS 001 mid, but I just can't seem to get any kind of consistency at all. FYI, I'm a 4.5 level player. Problem is that I have an extremely hard time producing enough spin to keep the ball in the court with anything but poly strings. Kick serves are very difficult to get going unless you really put 100% effort into every serve. Anything less just doesn't cut it and the serves tend to sail long. I'm quite short (5'6" tall), so I really rely heavily on my kick serves to get me through my service games. But since I typically use a nat. gut/poly hybrid, the spin just isn't there (compared to the power). At first, yeah, the stringbed is adequate, but as it breaks in, I lose that spin potential quickly. I play a lot of doubles and really like the feel, touch, and power of a natural gut/poly hybrid, but I am struggling very much on serves. But with poly, I can blast some real bombs almost without even trying. The issue is that I lose all feel, touch, and power with the poly strings. Anyone else have any problem serving with this racquet and if so, what are you doing to change things?
