I have a pair of Rossignol Rebel Freerides 177cm. They're about 90mm, 69mm, 110mm so pretty narrow. The skis have a rocker tip but a flat wait and tail. I'm 6'0 and weigh 175 (below average for my height).
I'm a beginner to intermediate skier with a moderate amount of inbounds experience. I'm not an aggressive skier and I don't go for speed. I live very close to the west side of the North Cascades and have very easy access to some great backcountry skiing destinations. My goals are to do day-long touring trips with some summit trips. Ex. Mount Baker, Mt. St Helens
Right now I have Salomon 700 bindings on the skis, which are alpine bindings. My plan is to replace these with touring bindings and purchase boots as well.
Does anyone have any advice on whether these are capable of using in backcounty?
How heavy are the skis? There are trade-offs when you start to shave weight. Less weight means more efficiency on the up--where you'll be spending most of your time, but the down may be compromised a bit in terms of skiing performance, dependent on conditions. E.g., light-weight skis don't bust through crud very easily, and you may get knocked around. On the other hand, too heavy, and you will feel like you have led weights on your feet at the end of the day, and you may not make the summit.
A flat tail will gives you more effective edge, which is good for steeps, but it also depends on the turn radius.
Carbon fiber boots, carbon fiber skis, and a light-weight pin binding, I think, make a great setup if you're going to do long day-trips to summits. You have to learn to ski a bit differently, though. The boot won't go to work for you as well as a dedicated resort boot in driving the ski. You almost have to learn to ride the skis like a surf-board in some cases.
