There are two things in life; snowboarding and things that revolve around snowboarding. I'm 6'2" 165lbs. my powder board is a Ride Decade 160cm with Burton Missions and my fun board is a Nitro Haze 154cm w/ Ride Deltas. Boots are DC 11's. I enjoy the park but riping through the trees in the backcountry is home.
Zack, I am on my second Nitro Haze and I ride it everywhere. If you are looking for a dedicated powder board you will probably want to go with the "yes" stubby. The Haze is my go to board for everyday riding!
Don't worry so much about height. weight is more important and your riding style. If you want a park board 150 should be great. if you want an all mountain board you may want to size up to the 153cm. hope this helps
