Im 6'1, 195lbs size 13 boot and i ride mostly groomers but im trying to learn the park this season. Im a intermediate rider who normally ride a 158, what size board should i go with? I have spoken to some DF gear experts who Ski (no snowboarders were available) they recommended a 156. The Dark series only comes in a 155, will a 155 be too small for me? Im not interested in speed just carving and learning the park.
