Looking at picking up a pair to use as a touring ski and trying to decide between 180cm or 188cm. I typically like skis around 185cm, which should point me towards the 188cm, but my buddy is suggesting I go shorter for a touring ski to save weight (ski length and skin length). I'm about 5'11" 220lbs and will be skiing mostly the Tahoe area. Also, is there a big enough difference between the 18/19 version and the 19/20 version. Seeing some great deals on the 18/19 version.
