They will be fine for you. I rode them (last years, 07/08 model) last season a decent amount and they are a very sick ski. If you want a one ski quiver (and like soft skis) these are for you, no doubt. I'm 5'9 150 lbs. and had them mounted at like -1 or -2 with Jesters.
Park: they work fine (not as good as Anthems but not half bad), I didn't take them on big stuff or spin more than some 3's but they are a blast, also didn't take them on rails cause they were my only fat ski for pow. Learned butter 3's on them.
Groomers: Very very good, even for being this big, they have a massive sidecut so they are very turny. Don't hesitate to ski them anywhere.
Deep pow (3 feet+): Very good, I mean they are 115 underfoot, they float great. Good for cliffs, I only did 15 foot or less ones though, so I can't vouch for big ones.
*note* There was a small amount of tip dive sometimes because I mounted them close to center, but that's cool cause I use them as an all mtn. tool and got Donner Party's this year for my pow needs.
Glades with pow: very sick due to sidecut, they turn on a dime and don't feel as big as they are.
I would consider these an all mtn./pow ski, that can also ride park fine, but there are better skis for park. I think you would have a lot of fun on these skis. I skied them in the PNW pow, and in some really light pow the one time last year that we had it. I consider these skis an in-between ski, like something you get if you already have a park/groomer ski (something like 80-95 underfoot), and you already have, or are going to get a 100% pow ski such as Donner Party's, ARG's, or any other really fat ski with rocker and hopefully reverse sidecut.
