I'm a 4.0 (used to be 4.5, and maybe will be again) who doesn't exactly like change and have played with Leona 66 for probably 20 years now. I'm trying to find a replacement racquet, and wondering how much the string affects all these demos I'm trying. I used a Yonex RA-5000 because my playing partner insist I use it (I don't think it was from the U.S.). It was strung up with what I thought was NXT Max (white string) and the racquet hit pretty good. And I am not one who likes very wide beam racquets. Also, I realize that many people see Leona 66 as a garbage string, but with it being pretty soft and all, if I string up my racquets at 70 lbs, what tension is that equivalent to with "real string". Will using a "real string" (16 gauge, etc.) get me more spin? Right now I'm leaning towards maybe the Slazenger Pro Braided, Wilson 6.1 HPS or maybe the Tour 95 racquets. Any input and/or suggestions would be greatly appreciated. Thanks.
