I am looking to replace a pair of 172cm 2010 Line Prophet 90's that were sold to me a couple years ago after taking a several year hiatus from skiing. To put in perspective why I might have made such a mistake buying these skis it is becuase I had no concept of what it was to have a shaped ski. I was told to go much shorter than my old skis (a pair of 210cm straight sided skis) and the LP 90 172's were sold to me. Now that I have learned much more about myself as a skier and boosted my skills again I am having a hard time narrowng things down to a ski that might be best for me. I am 6'4" and about 235lbs. I am an East Coast skier and ski Jay Peak, Smuggler's Notch, and occaisionally Sunday River. I am looking to buy a ski that is great in the trees and for the groomers. I am looking at the Line Influence 105 or maybe the Icelantic Shaman and it seems these are great skis for what I am after. I am wondering if people think this might be a good ski for someone with a build like me. Also, what length might be good? They seem a bit short for me and difficult to control. Any constructive suggestions would be helpful!
