Sorry to have been off for a few days - work, etc., sure gets in the way, but did get to ski Mt. Snow today w/ my club - x l ent conditions, even ate lunch outside on the deck! Did some bumps, or really, bumps did me, it was ugly...
DO try to demo some skis - Wawa has a great demo program, and many types to choose from. Yes - lengths have changed for the shorter, and there are reasons that they work well shorter - the parabolics practically turn themselves! Talk to Mike Vlass in the shop, he'll listen to your skiing habits/skills and make some suggestions for you. I believe you can demo all day long, as many pairs as you want, 40.00. Should probably only try 3 pr., give yourself time getting some good time on each..
Don't buy anything now - good deals on this year's stuff are just a few months, if that, away. When you decide on a ski, wait it out, buy them when they're new but 'last year's' model. Saves so much $.
Still hope to meet you at Wawa at some point, or can point you to my other, who skis AMs.. Let me know - I think we're all about the same age, it'll be fun to have new ski buds! ;)
