With all this new racquet technology(or gimicks) I am so confused as to what I should about a new racquet. Currently I am using a dunlop M-fil 300. But I feel like its not stable enough and not quite powerful enough for my liking. I have been looking at all sorts of racquets to demo, but there are way to many choices out there. My question is, do all these racquets really make that much of a difference? Or is it all about the player? Should I demo more racquets or just find one and stick with it? I just don't know what choice to make. And I don't think I'm alone. Demos so far: rds001 rds003 m-fil300 ag300 Then there is string, I have been using klip excellerator @57lbs, just because I am afraid to make a mistake choosing new string. I want power, comfort and feel, but I don't think I am ready to shell out the $ for gut. I also don't break strings enough to ''experiment'' or have the $ to do so. What are some safe options. I also don't think that companies, like prince who come out with three lines of racquets in about a year and a half are helping us consumers. There are just simply too many options out there. I am just afraid to make a wrong decision. What would my best choice be?
