Brandon,
The EVA gets dented because of the opening in the cup is too narrow, I haven't fixed it yet but if the opening was to be cut just a fraction wider it would solve the problem. The denting seems to only occur when popping and not when you are fighting a fish but it seems as though it could have been a easy thing to solve from a manufacturers point of view, maybe there is something behind Carpenters way of thinking. It really is a great belt though and I wouldn't swap it for any other.
Steve.
