Replying to Mr. Pollard's Opus too burly for dynafits? Touring people please help

I'm getting a touring set up soon, and have been having trouble finding the right combination of ski/binding. I'm for sure going with dynafits, because it will be an almost entirely backcountry set up, but for the ski I'm not so sure. I love the feel of rockered soft fatties but I know that will sacrifice performance of a touring ski when you're going up, so I've been trying to find a happy medium for the way up and down, and have heard nothing but good things about the opus. The only thing I worry about is the opus' are pretty big skis and have some weight on them, and the dynafits have a somewhat limited din, should this be a problem? I'm 6 ft and 175 lb, thanks in advance!
