I have a board that is a very good rider. It has a glass on fin. I've recently become curious about how it would go with other fins. I kind of feel like cutting off the old off and glassing another on or maybe just getting a box installed. What's holding me back is fu king up a good thing. The dilemma is basically my typical m.o. of nothing lost nothing gained. Anyone done this to a favorite board? If I go the box route I can get a box version of what I have glassed on so not a huge risk.
