So I weigh roughly 130 lbs about 5'9 or 10. I've been snowboarding for about 3 years on a 151cm board and Im looking to get a new one. I found a 154 that I like and a 150. I mainly free ride but I do like to occasionally hit some rails and such, and I am really getting into jumps, would 154 really throw me off and would the 150 just seem to small or something? Been riding for almost 7 years just the last 3 seriously and want some advice sine no one has ever helped me really before, just did my own research.
