this person is correct. this was my park setup this year and definitely the lightest setup you can get. and getting a light setup doesn't mean the ski is beating you. it's just, why would you cause yourself the extra trouble of a lot of swing weight?
my level of radness... it just can't... be quantified.
Quit rippin' on the kid because he wants light stuff. Maybe he's a small person and trying to grow into bigger skis. When it comes to weight, it's all about proportion. Two years ago I got some Trouble Makers and thought they were pretty light. A year later and 50 lbs lighter, the same skis kicked my ass the first few days on the hill. I was surprised that it could make such a difference. True, the better skier you are the heavier skis you can control, but don't worry very much about weight. You have your three basic groups of twin tips: Park, All-Mountain, and Powder. Within those groups, the differnece in weight is pretty much nonexistant on the snow (i.e. you won't notice it when you're actually skiing.)
