Hello, i currently ride a ben chetler 100 but it is way to heavy for the mountains we have in quebec. I am looking to change thoes one with an helio carbon. i am really in between 88 an 95. Witch one do you recommand ? I'am 5"7 for 200lbs and a usualy ski undergrowth, and sometimes in groomed. My boots are salomon slab, and i plan to change my fix with helio 350. Is 162,161 seems a little bit short and 170s a little long ? thanks
