Stay away from Fiberglass. Nothing from horror stories.
I guarantee someone will say "YOu dont know what your talking about, a well done fiberglass kit is better than urethene"
Yes, however, do you really want an extremely heavy kit or do you want a kit that isnt too heavy and will still last?
Go with polyurethene kits. Im sure you can find the buddy club in poly, just have to look harder.
