So I just restrung my poly cross for the first time ever in my racket with NG mains. When I strung my racket for the first time, I used 55 lbs for the mains and 51 for the crosses. I restrung my poly crosses @ 48 lbs (Pd GT, 16x19 string pattern) I noticed (5 min after stringing) that my frame is now 0.08 inch smaller than it should be. The length of the frame is still its correct size, but the width is not correct. Is this a problem? Is it, for example, possible I will brake the frame when I'll play with it. The crosses will lose tension in the next 48 hours, is it possible this process will restore the width of the frame to its original size?
