Hi everyone. I just thought I would give a quick review of the Iso-Speed Baseline Spin string. For some background info, I am between a 4.0 and 4.5 player (more close to 4.5), I play mostly from the baseline, and hit pretty hard from both sides. I use a KBT in stock form.I bought the reel, looking for a pretty good poly and an amazing price. And folks it delivered in all areas. It had had great spin, and good touch. The only thing that it did not excel in was having good "pop". You did have to swing pretty hard for it to really jump. But other than that, it was a very good string. I would recommend to all who string there own racquets. I have one racquet with a hybrid with Ashway Liberty, and it plays very well. That is a little softer, but probably won't be as durable. Thought I would give the review as many have wondered about the string.
