Nice review! Can't say I'm surprised about the topsheet though. I checked out the board pre-season at REI, and even on brand new boards on the shelf, a couple of them already had bubbles formed underneath the topsheet. Is it chipping from the edges? Not sure there's much you can do other than repair it as it occurs with some epoxy to keep it from spreading.
