I've only gone in the backcountry twice so far, so I can't say for sure what the backcountry's usually like based on my experience, but from what I've ski'd and from talking to other people who've skied in similar areas what I'll be going on tends to have soft snow, ranging from ankle to knee deep untracked, gradual to medium steepness (I'd say equivalent to the steepness of a typical whistler blue or black run), and would generally be wide descents, about 60% of which would be bowl skiing.
Hi - Based on what you've bolded, your next post with the 60-70% frontcountry figure, and my experience with the back bowls etc. at Whistler, I'd say you'd want something that's on the light side but not a dedicated touring ski, and something that is stiff enough to hold up to Whistler's heavy snow. Think your original 100-something idea is spot on.
Partly agree with Phil and others about AT and bumps, with the caveat that it depends on the bumps and your motives. Plenty of good skiers on AT or tech hit major air, work through soft bumps, and do just fine. Worst case scenario is that the binding will wear out in three to four years. OTOH, most of the lift served runs at Whistler only have bumps in places, or sporadically. If you're actually looking for bumps, then you just have to arrange for two skis, get the front side all mountain first. Sorry but is what it is.
Anyway. Allowing for your budget, I like several of the ideas already out that mention lighter, all wood or wood and carbon skis: Hell n' Back, Kabookie, Theory, in particular. I'd also check out some of Prior's skis down the road at Function Junction; the Husume is well regarded as a crossover AT ski, and they're having a sale these days. It's a bit wide (109 I think) but deepish sidecut and locals like it for what you seek. Finally, Praxis is having a sale, and they make some great backcountry skis. Check out the Yeti.
