At 170 lbs get a 156 Westmark if you wanna ride a ton of park. At 145lbs I could charge comfortably on the 150.
Ride rocker like a skateboard, it will feel different than your camber. Drive between your feet, and ollie more like a skateboard, don't lean'n'load ollie like you would camber.
It is one of my all time favorite boards.
