I dive an HP100 with a 19 bLailout bottle. I do not use a octo off my main tank. So currently the pony 2nd stage is on a necklace under my neck and my primary second stage is on a standard length hose. So this works great for me but not so great for someone whom I may need to one day extend air to. The hose on the primary 2nd stage is just too short to facilitate a smooth and comformartable donation. So I have decided to switch to the lost hose configuration on my main tank. Hence my quesiton. Given that the long hose will be coming off my main tank (center of back) how does this affect the length of the long hose I should use ?
