Next best price is here:http://www.coloradoskishop.com/Icelantic-Da-Nollie-Skis-2015-p/danol15.htm
for $449. Id go with the 170s. I have the exact same skis in a 170 and I'm 5'7 and a little lighter and i ski the midwest as well. The rocker on these will make them feel a little shorter so the 160s are a for sure no go.
If you do go with the 180s, they can be found on that same link. Looks like you missed the $299 deal which sucks, but $449 for them is still $200 below retail which aint bad. You'll enjoy these for sure.
