Not trying to pick a fight (it just the New Jersey in me).... But Dawg that's for you - aren't you doing the advancing skier a disservice by making proclamations that sound like they apply to everybody: maybe someone prefers short radius turns or slower skiing (that's me) or wants to get better in the bumps. I can't believe that the 180mm wouldn't be too long for anybody like this except for a very strong and/or heavy expert skier (then again that jump down to 173cm is pretty big).
Was the "jockey" you mention an expert skier, hard-charging advanced skier, or and advancing intermediate, cause if it's the latter a good argument could be made that the 166cm is more ski than they need (that ski is 6cm's taller than they are). I'm just trying to understand this predilection (almost a bullying) around here to "go long". Note - I'm probably just damaged goods trying to get even for all those years in the 60's and 70's when I was skiing 190 or 195cm skis and could never figure out why I couldn't get my skis to do anything 'cept go straight.
He is a pretty fit guy, 60-years old though.
