My dive buddy was kind enough to bring his doubles set-up to the quarry so I could get some practice. He's about 40 pounds heavier than I am but other than that we have a similar build so we figured I could get away with diving his gear without adjusting the harness. This was my first time with a long hose configuration so he reviewed how to donate the regulator. I dove with two buddies since I don't have enough coordination when maneuvering in the doubles to be able to handle an emergency unless it happens right in front of me. I had one buddy carry my camera so I would have some pictures of me to present for your amusement here 
Things I learned on this dive:
It's going to be a long time before I'm comfortable diving the doubles but it gets a little better each dive.

Things I learned on this dive:
- I don't like the power inflator button on the "outside" of the hose, I like it near my body where I can press it with my thumb.
- The harness needs to be snug against my chest. His gear was slightly loose on me and even with the crotch strap the tanks shifted as badly as they had when I dove without one. Had the harness been snug there would have been no need for the crotch strap.
- It's impossible to see a buddy who is not even with your head/shoulders. My guys were diving together in a position where they could see/photograph me. When I wanted to see them some serious gyrations were required and it took me several seconds to regain my body position afterward.
- I really have to focus to do the smallest thing...like kick. My main concern was my breathing followed by buoyancy control and I was concentrating so hard on those I kept forgetting how to kick.
- It's hard to get vertical and when I want the air out of my drysuit legs I tend to go vertical. That resulted in a wrestling match at the safety stop.
- When you're only wearing one fin at the surface you tip over sideways...at least I did :shakehead
