On Ebay (using the awesome "Raceboarders.com" ebay button), there are two Rossi VAS boards, one a 167cm and the other a 168cm. A few of us, including myself, are a little bit confused as to model year of our own Rossi's. My board looks like both of the ones at auction but I doubt these are the same model year. Would a manufacturer build two boards so close in length in the same year? I dig my R159 and would consider bidding on either of these (R167 or R168). Anybody know the differences?
