as far as park goes, what kinda ski do you want?? A soft ski such as fujatives/invadors, or stiffer ski such as PE... which ski is going to pop better on takeoffs and stomp landings smoother??
it depends what your skiing? For park i love having something soft so u can do butters presses ect much more easily. For deep pow a soft ski will also be good(but so may a stiff one) as its much easier to handle but for big mtn and charging big lines a stiff ski is much better. It all depends on your personal preference
So to answer your question. Soft. But thats my opinion. It also depends how big you are. a Big guy might not get the support he needs out of a soft ski like a fujative/invader.
go for the chronic or chronic wides..they sound like what u need.The have a carbon ollie band for more pop they dont wobble on rails and landings they wont flop around on either.They will also perform awsome outside the park.
