Re: skiing on easy groomers -- a good brace helps a lot. My wife, who is no shredder, skied yesterday for the first time since her blown ACL, and she said the brace helped hugely -- a great confidence-builder. She has a custom-fitted one from the ortho people here. The surgeon told her, "Stick to the greens," but with the brace she was comfortable on blue.
She'd have done easy blacks, too, but for the conditions: a dusting of man-made over ice. (I had a long slide that ended head-down 50 yards below the fall. Gotta tune those edges.)
