For all mountain stuff, the chronic will ski better than the TC. Bear in mind though no ski you've hit rails with is going to ski groomers as well as well as they could without being slammed onto rails.
I have exhaustively searched the world wide web, and have come to the conclusion I cannot get the Chronics. Considering I am only 143lbs, do you think I could get away with the TC all mountain? I know they are soft but I won't be able to flex them a ton since I am very light, should be sweet?
