The factory strings on the 06 Mathews really aren't that bad, they don't seem to creep/stretch much at all. The serving does seem to be of poor condition though. Blow ups like this aren't common, I have sold and serviced a lot of them and seen a few come in for serving problems, but never have I seen one blow up like this. The few string problems I have seen on 06 models that were bought from us Mathews stepped up to the plate and took care of the problem with no questions asked.
