Hello, I am 19 years old and have been skiing all of my life and consider myself an expert skier. I'm 5'10" and 170 lbs. I currently live in the midwest but typically get out west atleast 1 week a year. My skiing in the midwest is limited to 80% groomers and 20% park skiing but when I go out west I typically spend my time 40% powder, 30% glades/tree runs, 25% steep groomers, and 5% park. I am looking for one ski to do it all. I have been eyeing the Line Prophet 90 179 or 186 but I'm afraid its not an advanced enough ski for me. Any suggestions? Thanks!
