I have two SRD Tour 95's. Love them. Have some serious heft to them. TW states 12.5 oz, 327 SW, 62 Stiffness. My groundstrokes were always hit with some pace to them, and serves were pretty. One thing you must do is, as with most if not all players racquets, to prepare your strokes early. You can't cheat.
Haven't played any of the RDS line but have the RDX500MP. The SRD is much heavier to swing and does carry more pop. You can spin the crap out of it but I have always felt that it's due more to the square head than anything else. I also have an MP Tour 1 98 and it does compare slightly to it. However, the MP does play slightly lighter... slightly.
If I were to compare it to a current line based on numbers alone, it might be the RDS002 Tour.
