I am looking into buying new skis this year. I have done a lot of research and I like the Line Prophet 90s. The only thing i am worried about is getting on my edge in the hardpack. My old skis are 72mm at the waist. I am looking for something to get a little more off piste and advance my skiing a bit but will still want to rip the groomers on days I ski with people who like to stay inbounds. Anybody who skis these know if I will be working way too hard to get on my edge? I am 5'9" 150 and an intermedate/advanced skier that skis on the East Coast. I have never been out west though I want to make the trip.
