I use the 70-200 2.8L IS II on a 7D with a battery grip. I carry that and a 60D with a wide angle & flash on many assignments. The weight would bother me if the images weren't as good as they are, but the truth is that I am so happy with the images coming off of the 70-200 that I have no ill feelings towards it at all. It's just a matter of physics that if you want that focal range with that f-stop and image stabilization, you are going to pay in more ways than one. But at the end of the day, it's the one lens I know I can count on every single time.
