I never thought i would say this so soon....I was originally going to buy 2 more of my RDS 001 MP but decided to demo just before i bit the bullet. My local store charges $25 for a 1 month rental and once you finally decide and buy a racquet the charge comes out of the price of the racquet, so you dont lose anything. Ive basically tried/retried every frame on the market just to verify that i was indeed sticking to my RDS, but the Fischer has changed my mind, i still have a bit to decide but its an almost certain decision. Groundstroke wise the Fischer just felt more refined in every manner, spin was a little overwhelming with the RDS in some cases, where as the Fischer still gets good spin but not as much, with the Fischer I was getting lower net clearance so i was hitting with a bit more pace and depth. The Fischer did wonders for my 1HBH, it felt really natural with the ball pocketing compared to the crispness of the Yonex. The added weight made it feel alot more solid and stable from the start, on the RDS i was altering it with lead tape which took some of the original feel of the racquet. Volleys/half volleys really benefited because of this, the RDS was great for put aways but the M-speed was even greater for touch. I was placing great on my mini tennis drill i did the other day. I cant comment as much for slices because my RDS is strung with 17g poly and the Fischer demo is strung with a 16g multifilament, personally find any frame strung with a fine poly to slice effectively, i never slice alot with my BH anyways. In the serving department the RDS deffinately had more pop, i want to clear up that the M-speed is NOT a weak serving racquet as in terms of power, its higher than average for most player frames. They both give a very rewarding loud THWACK!! when struck, these two racquets give the loudest boom out of any other racquets ive tried. It actually misleads you to think your serve is generating more pace than what it is, but its just something to do with these two frames contruction. I guess its also a little intimidating to your opponents when they hear such a boom. I felt my flat serves were a little more consistent and controllable, but i recognized that my kick/slice serves lacked alot. Overall i felt the M-Speed Pro 98 is a better racquet on top, and ill be buying 3 for Christmas. I just liked to share my experiences with it so maybe others will give it a try. -Also the M-Speed is ALOT better for my TE which has let up on me alot ever since using it.
