ive been competing since i was five, and won regionals at eleven (western thirteen states) and seventh at nationals in slalom. the only thing that takes second to snowskiing. this just seemed like a good place to brag! my bad
dude, im 5'6" and i just moved from 146 to 151 and i love it. i think you'll be fine its just preference. although sometimes the backcountry owns me. my advice would be not to center mount them if you think theyll be too small.
