I really can't believe some of what I'm reading. I string on a Neos and have never had a Head racquet "compress", or any other kind of racquet. Stringing 10 pounds higher to compensate? What of the end result?
Guys, short of it is, anytime a racquet compresses or shifts or the shape is different, then it is NOT a good thing. It's hard enough on a frame just stringing it normally, but all these suggested "fixes" are just plain scary. The problem here is either the mounting system used, or the way in which the frame was mounted.
