I'm coming back from a layoff after an injury. I'm a 3.5/4.0 player. Since my return I've used a more powerful racquet (stiffer, higher SW). Now that I'm 90% or better, I'm finding it difficult to control it. It seemed perfect when I was swinging a bit slower. My question is should I continue to try this frame and swing a bit slower, with more spin, or go back toward a frame that I can swing out with often and keep more balls in the court? The main differences are increased stiffness (63 to 70) and length (27.25 to 27.5). I'm primarily a baseliner. Some positives are that I can generate more ball speed with less effort, find it easier to maintain depth, and the racquet is generally more stable. The negatives are that I make more errors and lack feel, which isn't helping my confidence at the moment. I'm experimenting with different tensions now. Thanks!
