hey,i'm an intermediate level rider looking to buy my first board. i'm 5'8, 180lbs, a stocky guy basically. i was reading up on board sizing and they said weight is the most important factor in buying a board.up til now, i've been under the impression i needed a board anywhere from 153-155. after using your sizing calculator, it suggested 158-160 which makes sense…can i get some opinions? i'm 5'8, 180, boot sz 10, freeride, male
