I'm looking to pickup a pair of 2013 RTM 77 or 80s. Does anyone have either of these (or even better skied on both?) that can recommend? I'm an intermediate to semi-advanced, spend most of my time on the east coast and make it out west a few time a year. My gut says go with the 77s, but I've seen pricing close enough between the two that it got me interested in the 80s.
