I was flipping through JJ's Fundies book and it seems like the pictures have several different methods of securing the second stage on the stage bottle. A Google search provided some images, but no real information. In some cases, it seems that the hose is stuffed in the restrictive bands with no further attachment. Some images show the second stage with a bolt snap, and in one image, this bolt snap is jammed (not clipped) under the restrictive bands as well. However, other images show the second stage without a bolt snap at all. I'm sort of curious about the discrepancy.
Also, I noticed a lot of the stage bottles had Yoke regs on them. I can sort of understand that minimizing overhead contact is less of a priority for stage/deco bottles, but wouldn't it be preferred to have the same connection on all regulators for interoperability? Or is it because aluminium stages might often be rented and therefore equipped with Yoke already?
Cheers. I'm sure I'll get some "ask your Fundies instructor" responses, but these seem sort of beyond the scope of Fundies, and not all that terribly important anyway.
