.never admit to forgetting to wax up
at least he did'nt put wax on the bottom for speed! and yes, i have seen it done!!
So would it be worth getting a foam board
not all foam boards are equal, an 8ft swell which most schools use (at least they do down here) would be like a supertanker to the one you link to.
welcome to surfing though, frustrating is'nt it!
