I've been away from tennis for a bit and I currently own an old Spalding GC-20 (1982ish) and am looking for a replacement racquet. I've tried a few tweener racquets and found them too light for my tastes because I am used to the weight of the GC-20. I just couldn't generate enough head speed with the lighter racquets to get good depth and spin. I feel like I would have to shorten up my swing a lot and punch the ball more using alot more wrist action than I'm used to. I can't imagine that would be good for my elbow in the long run. I would like something a bit easier on the wrist though than the GC-20 is on the serve. I just can't snap my wrists like I used to. From what I can tell the specs on the GC-20 are: weight: 12.5 - 13 oz (likely on the heavier side) length: 27 inches stiffness: ??? (though very flexible from what I've learned) balance: 9pts head light string pattern: 18x20 size: 85 sq. inches I'm a 3.5 player and I have a general all-around style and tend to hit the ball flat, but like the ability to generate topspin when needed. Racquets I'm thinking of demoing are: ProKennex Ionic Ki 5 PSE ProKennex Ionic Ki 5 ProKennex Kinetic Pro 7G Wilson K Factor KSix-One 95 (18x20) Babolat Pure Drive Roddick Dunlop Aerogel 4D 200 (2Hundred) What 4 should I demo and are there others I should be looking at instead? Thanks for the help.
