Crap - forgot to add a comment about bindings...
SL = Burton C02s: I like a firmer binding on this board so I can really crank on it at speed and get that responsiveness.
Proto = Burton Prophecy (Re:Flex): I went with a softer binding with more flex/board feel for the Proto. I like them a lot but sometimes I miss the better responsiveness of the C02s. I think that is just personal preference and riding style.
