To the threadmaker, people are trying to help you out here, so be a little polite, and answer the questions they are asking you if you expect anything in return. I realize this is the internet, and its great to feel tough and macho, but lets get real, pretending to be super awesome-tastic like you are is pretty lame.
actually it would be the live lifes. Those are WAY too fat and not SUPER stiff. I don't know a single park ski that's super stiff, but the line chronic blend would be good for you if you want a good stiff ski that can handle all.
get a pair of head mad trix they are super stiff and burly.. and I have karma's as well i dont think they are very stiff at all... definately stiffer than my ar5s or troublemakers but still not super stiff
