Don't worry about the top sheet delaminating. No need to worry about these minor top sheet blemishes. I like to call them battle scars as well. My wife and I got no boards and yes, you get a bit anal right away with new sh*t but after a while you will enjoy using it for the purpose it was built. One time I was goofing off (not paying attention) and my wife clipped my tail and left a nice scar. Yeah I was a little upset to begin with, now we just joke about. The lesson being; have fun with the sport, and don't sweat the small stuff. You'll find it hard to just relax and have fun when you sit and worry about little things like this.
