I have not skied them, tho I hear they generally hold well on ice/hard snow and good in variable snow conditions. At your height and weight,
going up to the longer lengths ~180ish is not a bad idea tho. The nomad line varies tho, you have some range from soft to fairly stiff..Check out reviews
from people around your weight that ski hard. Google search for video reviews of different ski lines, then you can see how the reviewers ski.
