im having a problem deciding which size ski i want and i was hoping you all could help. i am 6' 160 lbs. im an aggressive all mountain skier. i cant decide whether i want the new seths in a 179 or a 189. ive been skiing on 4frnt msps in a 180 for the last 3 years and last year i definately felt like i could go bigger (ski wise). my only hold backs are: will i still be able to rip through the tight trees? and will i still be able to throw them around in the park? any input would be appreciated. also anyone who already owns some seths feel free to fill me in on the money spot for mounting. peace.
