Zorba's goal seems like the best solution. Rent the adjustable stands and then order the height you like. The single piece towers be lighter, stronger and have less parts to get lost and or break. While there is a lifetime guarantee, breaking/losing something on a multi-day would suck.
I figured that was a plus for the multi- part configuration... Spread the risk. If you have one spare, you can replace any portion of any that could break- on the off chance that, while portaging, you managed to drop a the raft off a cliff you'd have a better chance at patching together 2 working sets from 6 pieces vs. three if that makes any sense.
Just to be clear about the materials and strengths here, when was the last time you worried about breaking a caribeaner? those are made with the same aluminum, just much less of it, and the vast majority of them are strong enough to lift a pickup (the old oval one I have on my desk is 22n KN = 4900 lb!) . Granted, there are some very cleaver geometry tricks they use in designing them, and most won't do nearly as well with the gate open, but I have easily double, close to triple the material cross section in these.
Another fun tidbit about screw strengths is that 3 threads on a 1/4-20 is strong enough to lift an engine. These are all 5/16-18's with a lot more than three threads
The funny thing is I actually logged in to post some more pics 'cause the angled heads came out of the machine friday! this one shows the 1 1/4" and 1 1/2" bases and the straight and angled heads for comparisons. (yeah, I know my desk is a mess!)
