Just out of curiosity, how many string sets do you typically go through in order to find the proper tension? I bought 2 sets each of a variety of strings (synth gut, poly, multi) and I have yet to find the right tension for any of them. I came close with the poly, but after a short time, the tension got lower and the control started to fade away. I was hoping to find out which type of string I prefer, but all that's happened is that I've been struggling to find the right tension -- I haven't even gotten a real chance to evaluate each string on its own merits. It seems like I should have bought at least 4 or 5 sets of strings just so I would be able to find the right tension for each particular one. But that's crazy. So how do you do it? For instance, the middle of the recommended range for my racquet is around 58. I installed a set of Ashaway Dynamite 17g at 50 and it's like hitting with a piece of steel. Sure, it's got some nice pop and decent control (nothing special in either case), but my arm felt like it was going to fall off after 15 minutes of hitting. And here I thought it was supposed to be a "comfortable" multifilament! The closest I came to finding something that was in the right tension range was the SPPP 17. But after around 30 minutes of hitting, I could feel the strings getting looser and the balls started flying on me. So there's no doubt that I'll have to install yet another set of SPPP in that racquet at a higher tension just to find out how good the string really is. Is there some method I should be using to go through these strings? I thought at first I could just build off of my current setup and vary the tension slightly from there, but it seems that when I go lower by 4-6 lb., it's just WAY too low, and when tried the Dynamite even 8 lb. lower, it was WAY too high. I sometimes wonder if that's what makes people love or hate a particular string: the fact that they didn't quite use the right tension. That is, people who hate one string while another person loves it might just be due to a couple of pounds of tension. And how many people go through 4 or 5 sets of the same string at different tensions just to try out a new string?? Sorry for the long post, but this is getting a bit expensive and I'm still no closer to finding the proper tension for any of the strings that I've tried... I originally started with 8 and I've only got 2 sets left!
