Thanks, I didn't get what you mean by 160 won't be fun, do you think is too small or too big?
haha, cryptic information alarm
Didn't want to say that bigger or smaller is better, but to mention what I know about this distinct size. 2nd try: The Custom X is kind of the standard board of the guys I'm riding with, all about your weight, they all had a 160 at some point and love the board for ripping groomers (they're into carving n speed). So if this is your main
aim, you'll love a 160 Custom X.
But they were not too delighted hitting deep
(40cm) pow with it. It's surely doable, but you'll need to stay in the backseat (lean back a lot) to keep the nose afloat (= not too much fun). Can't say if a bigger one would be better (well, logically a bigger would float better, but then you compromise with agility), rekon it's more the shape than the size...
Just wanted to mention, that there is a compromise, and it depends on your aims, if and where you want to make this compromise. If you mainly aim at groomers, you'll love it. Also for riding some fresh left and right from the groomers. But if you want to frequently take it to deep pow (since you mentioned powder...), a board with a rocker nose would be more fun.
Husband now is riding a 164 hybrid rocker and not reluctant anymore to hit deep pow. I went from a 157 pure camber to a 158 hybrid camber and am delighted by its great float.
