So I'm getting a pair of brand new 177cm afterbangs (they're in the mail), but I have the option to size down to the 166cm model if I want to. From what I've read shorter skis will be lighter and easier to spin with (of course), but I'll wash out more often on larger jumps. I consider myself an expert regular skier, but only beginner/intermediate in the park, and at 5'9" and 120lbs I'm right in the middle of the two recommended lengths. Tld;dr which one am I better off with?
