I just got a Morey Mach 7-7, and am kind of skeptical about putting a leash thru it. When you hold it to the sun you can see the grid (instead of stringers) and I'm afraid if I break that grid it will make it break down/ crease quicker.

Anybody know one way or the other? I wouldn't mind no leash, but if it's not going to shorten the life of the board I'd like to have one on it.
