Definitely get at least the 178 if not the 188 (offered in men's). There is no difference between the mens' and the womens' other than the topsheet; even the flex is the same. The mens' dimensions are 115 at the waist in 188, but the same dimensions (i.e. 110 at the waist) as the s7w in 178. They ski very short due to the rocker. I'm 130 lbs advanced intermediate and the 178 is great for me so you will probably find it way too short at 180 lbs.
