one other reason ive been thinking about this holder:
I myself tend to move the weight on the racquets a lot, add lead here, take lead away, etc..
so the weight and the balance point change (more so than the string and tension at times)
this holder lets me modify the written label without the sticky mess, or label coming unglued
its a work in progress
it is a bit big, and the edges are not perfect yet, but it is holding like i wanted it to, lets see how long it lasts..
