How about a solo card?
I carry the tanks up and down the stairs and trails one at a time, but up on my shoulder, like a waiter with a tray.

In practice, yes ... particularly if you're diving in a team where you might need to donate one of those tanks to someone else.I see...but I am assuming that you want to keep them somewhat equal in pressure so both would have to be topped off.
The weight of air is the weight of air. I don't see how buoyancy characteristic of a tank will change the weight of air in the cylinder?If you sidemount and breath one tank dry and dont breathe from the other you might get a bit lop-sided though as one tank will have changed its bouyancy and the other one havent though? Depending on the bouyancy characteristics of the tanks that is..
But because I wasn't sure what setup I wanted, I stayed in backmount for a while, and started doing some cave dives with stages. What I found out was that carrying single Al80's up and down stairs and trails is actually HARDER for me than schlepping my doubles. I can't hold an 80 off the ground without significantly bending my arm, so I end up carrying them across my arms, which doesn't leave me any hands for handrails or trees or anything else to aid my balance. To my enormous surprise, I concluded that what I was already doing was the easiest way, for the most part.
Yeah good point on that. I suppose if using aluminums you'd almost have to move a couple weights off your belt onto the butt end of the aluminums to keep them from floating up.Good point, but Id imagine you would notice a bigger difference with a tank thats bouyant when empty vs one thats still a bit negative?
Interesting ... I don't own one. Been soloing for a few years now, and probably have more solo dives than most solo divers have total dives ... including solo staged deco dives.
I tend to avoid boats that want to "card" me to death ... if experience doesn't count for anything, I'll go dive somewhere else ...
