It's reassuring to read this thread in that it appears most double portage, as do we.  My paddling partner and I planned a trip recently with two young friends of mine.  In meeting with them to plan the trip, they were appalled when they learned that we double packed and they insisted they were going to travel light and fast, and suggested that once on the trip, we could agree to meet on some lake further ahead.  As we talked, it was evident that our styles were so distinctly it wouldn't work.  We ended up mutually canceling the trip. 

Other than that, the only comment I'd add that is not duplicative to past posts is the value I've learned in always packing the gear in the same location in the canoe.  Occasionally over the years, as we've prepared to leave a portage, I've noticed a "hole" in the canoe and asked where a certain pack was that always went in that spot -- and in the process avoided leaving gear on the portage.
