i find it easier to to switch ups on a smaller ski because of weight and how short they are. but since you 6 ft and the a bangs are a relatively soft ski, you will want as much stability (length) as you can. especially on jumps.
I am 5'10" and i ski 181 for the info
I MAKE CUSTOM DIECUTS, LOTS OF COLOURS TO CHOOSE FROM AND CAN MAKE ANY SIZE YOU WANT. PM ME FOR PRICING ETC.
