I totaly agree more companies need to have demoes. I would never buy a board without trying it out first since I have tried boards that on paper looked awesome but after riding it realized I don't even want another run on it.
Seems like the only brands I get to try around here are Burton, Capita and sometimes Endeveor. I ride burton and the gf rides capita, wonder why..
I would love to try mervin products but im not spending 500$ without trying it out first.
