Been checking out the Yonex racquets....V Core 100S and EZone XI lite 100. I love my Volkl Quantum V1 102 frame but I only have one and have had it for several years (bought it used from someone on this site). I'm a female about to turn 62, string my own racquets and am seeking a racquet with just a touch more power. I'm a 4.0 counterpuncher and trying to find a frame that gives my shots a little more power (so I don't have to work so hard.....hitting 25 balls to win a point). Does anyone here have any suggestions about a frame that may suit my game? I've been demoing the Babolats, but most of them feel like boards to me. I'm afraid my Quantum may all of sudden break and I don't want to be scrambling at the last minute to find a new racquet.
