hey all, I currently play the Yonex RDX 500 Midplus but was looking for some new sticks and was wondering whether anyone could compare the RDX 500 series to the O3 tours (mid and mp) and the Fischer M Speed (mp). When I last bought new racquets, it came down to the RDX's and the Fischer Pro Number 1. I sort of regret not going with the Fischer now...but whatever. I also hear some good things about the O3 tour. I hit with it very briefly and was sort of intrigued. Any opinions would be great. Thanks.
