Yes, it will be fun. If you have rocked fat skis in pow, then you might get frustrated, but I did'nt have fat skis until 3 years ago and shredded pow all the time just fine. Its more of a mindset thing. Like some people say, don't mount center and it will help prevent tip dive. but if you do, you'll just have to lean back. way back.
While I think you will be fine, you should think about getting something like the anthems, or kung fujas. though I used TNKs (centermount) for a few pow days this year, and they worked fine (it was only like 1 ft of night fresh at BOreal). They arn't hellbents though.
