What sold you on the happy hour?
Are you going to ride switch in any situation?
You also might want to look at the turbo dream, ultra dream if you hit POW as well. Also the Solomon mans board.
My friend loves the mans board. It is a bomber does well on groomers and floats in POW extremely well. It is a directional twin which sounds like more your riding style. I am extremely interested in the mans board because my riding style is very similar.
Just food for thought.. as for size 161 or maybe even a 163 because of the weight. Just make sure its not a wide model designated with W or X.
