Well actually I do....(I'm sure that doesn't surprise you!). The point is that the DIR system works for *all* kinds of diving (cave, wreck, open water etc.) in *all* situations (stage dives, backgas dives, scooter dives etc.)
I did a couple of double stage scooter dives earlier this year. With all the stages on the left, the stages were out of the way of the prop wash and you really don't know that they are there. With stages on the right, they would interfere with the light cannister, interfere with long hose deployment and interfere with prop wash and slow you down.
The streamlined argument doesn't only apply to scootering. It also applies to high flow caves. Now, if you've ever been in a high flow cave you will understand that you need to be as streamlined as possible (to such an extent that some of the "old school" Florida cave divers prefer wetsuits, don't wear bottom timers etc).
Being streamlined in the ocean may not be such a significant argument but (like everything else DIR) it's about the *optimal* methoology which works in *all* situations.
We shot some video while we were in Mexico which should show how the stages sit in the water. We weren't scootering and only did single stage dives, but nevertheless, when it's finished I can send you a DVD to have a look at if you're interested.
