looking for an all-mountain ski to deal with east coast ice, groomers, and bumps and a week or two in CO. been thinking about liberty morphics or helix, but not married. recs on brand, model sizes would be great. i'm 6' 170lbs advanced. most time on-piste on the east coast and on and off in CO, but i'm not hucking off cliffs. no real park play. thanks.
