I had the Champs for a couple days... they fit great but there's no way I could see the Fabric holding up well for the elk hunting I do. For me, they'd make more sense for sheep hunting and winter stuff. I always seem to come back to Whipcord... it's tougher than nails, is warm when wet, dries quickly enough and just does everything I could ask for a pant for 90% of my hunting. It also is a lot harder to get holes in around a campfire... most of my synthetic stuff is fairly ventilated from campfires!
I do wear a Supplex pant (North Face Tibet) that's great in the early season but mostly I've never liked Supplex beyond a summer backpacking pant for "evening wear"
It really doesn't dry out all that well IMO.
