How long of a hose for a reg on a pony bottle tank mounted upside-down and running to a necklace?

Umm, it needs to be just long enough that when you stick the reg in your mouth you can look left without the reg pulling, the actual length will vary depending on how you rout the hose and the rig you are using.

For tech diving at least, it's 40 inches.

Thats for a slung bottle though. No idea about an upside down pony.It has to depend on where the tank is positioned.

Take some cord or a length of rope and attach it to the top of the pony in the position you plan to dive it in and run the rope the way you would the hose. When it feels right, mark the line and you'll have your answer. You're configuration isn't real common, so no one's got a pat answer yet.
