fgray1:The hose should be coming from the right side of the first stage if your rig is normal. Run the hose down under your right arm acroos your chest then under your left arm then up around the back of your neck. Then into your mouth. To deploy you will only need to tilt your head down when you pass it to your buddy. If you have to receive rather then give a reg. you clip your primary to your bungy around your neck.
Good luck.

Are you sure you meant to say "under your left arm"? This not a usual practise. The hose routing is as everyone else above has mentioned. Do not route under your left arm. Just think about it for a minute and I am sure you can come up with reasons not to do so.
The benefit of this system is to be able to quickly and effortlessly donate your primary. If you run the hose behind you then you no longer have direct, unencumbered access to the hose. What if it gets trapped somewhere behind you. You cant see it or feel it behind you. Now this is how things go from bad to worse. Also the long hose set up comes from the "tech" side of diving and many times deco divers will have deco bottles strung under their left arm. Having your hose under your arm is just asking for problems.
Hope that helps.
