I have last year's Riders Choice and recommend it highly. It's an excellent all around board. I'm 6', 195 or so lbs and have the 157.5. I was stressing over what size board to get--everyone will tell you something different. You're in the middle of GNU's weight range for both the 154.5 and the 157.5, so you can't go wrong. I personally would put you on the 154.5, as it will give you a touch more maneuverability, but still allow you to bomb the groomers. Enjoy!
