Hey, just a quick question before I get my racket restrung again. Ever since I started using Isospeed strings, my cross-strings seem to be wearing faster than my mains and have ALWAYS broken first. I'm not sure if this is common, or if maybe it's a result of how I've been hitting but just wanted to get a little feedback. I string my entire racket with them and usually the crosses last about two weeks, yet the mains seem to be in good condition still after the crosses break. Thanks for any replies.
