Replying to Are urban punx really that soft?

in the freeskier buyers guide they said its pretty much a rail only ski, and wouldnt work on jumps or something like that. but that was probably some 35 year old skier who only likes stiff skis. but for someone who weighs like 150 how would they be on like jumps over 60-70?
and if anyone has skiied them how good are they for butters and stuff? im guessing really good, but how easy is it to like hold butters and stuff?
