Running a hose from a stage bottle under your arm to around your neck sounds like a pain to me. If you want to not change configuration, you can use an air2 inflator, that is what I do mostly and was suggested above.
What benefit does having it around your neck provide? Are you afraid you can not deploy the reg from the stage fast enough? One of the benefits of having a slung pony is the ability to unclip it and hand it off, which would be more of a problem if it is tied around your neck.
No, I'm comfortable with deploying the reg from the bottle. But before I started diving solo I didn't use a pony at all and had been using a longhose and necklace for the octo which I really liked the idea of and still do. Solo diving has led me to more training and in the future probably wreck or cave which will bring me back to a bungied necklace so I'll just keep it that way now.
As far as some people thinking three regs is an overcomplicated set-up and prone to mixing them up, I think leaving the pony reg stowed on the bottle is probably best for that not to happen too. Thanks for the help
