I'd say find a 175 range ski....perhaps a 180. It depends how comfortable you are on long skis.
Like it was said above, Vinnie Dorion is on 181s, and he's only about 5 foot 6.
I myself am about 6 foot, and I'm on 169s right now, but those are what I bought for my first twins. I'm going to get 180 range skis
The reasoning behind that is you have more control, and landings are more stable. You'll also get better control switch too.
Ski whatever you're comfortable with.
