Hi everybody. This is my case: I'm a racquet junkie, but ultimately I think I managed to alleviate my condition by using only these two frames. I defintively favors heavy frames, cause my long strokes match them better. I think is harder to keep a steady long swing with racquets below 310grams. The thing is, I play my best with k95s, but every now and then, when I'm playing really good, I feel like it's a tad too poweful, and a tad cumbersome. Then enters k90, really a great mid, less powerful and more maneuverable, and plays wonderful... for a while. The moment your level decreases a little bit, your UEs count starts to grow, so... back to the 95. Is anyone else trapped in this process?. Is there a way to overcome it?. Or... it is not really that bad?. By the way, I'm now an advanced intermediate player (champion of 3er. category in my club) with... you know, textbook strokes. Opinions will be greatly appreciated!.
