Hi So recently I've been researching quite a few different strings that would fit the Dunlop Aerogel 4D 500lite, or the Dunlop Biomimetic 500. With the lite, I seem to be having trouble getting the ball on the sweetspot consistently. Being only 9.5-6 ounces, the lite doesn't have much plow on any strokes. So, I was thinking of moving up to the Biomimetic which weighs in at 10.5 ounces or something. Since the Biomimetic would weigh in more, I'd get power, but I'm also looking for comfort and spin. I have minor tendinitis in my shoulder, so I was hoping for something that'd be easy on my arm but still offer me some spin. I have pretty good technique on all my strokes, and am working on lengthening my swing. I have pretty compact strokes. I have a semi-western grip on my forehand. So far, I have tried Kirschbaum Pro Line II, RPM Blast, Pro Hurricane Tour, Pro Hurricane with NVY synthetic hybrid, and prince synthetic gut. My favorite was the syn gut. I'm looking towards: Spiky Shark, Black Code, or Barb Wire. Which one of these strings offers the most spin but doesn't kill your arm? If you have any other suggestions that aren't these strings it would be appreciated too. Thanks..
