Hoppy:Shame we don't have more of the GUE guys over here, or maybe it's a good excuse for trip over there to do DIR-F, which I intend to do as soon as I can just so that I find out just how far I have got to go !
Cheers again guys

Hoppy we've done several classes in the UK and in fact we have a local instructor Andy K available. Andrew G, myself and Andy K taught a series of classes at Capernwary Quarry last November, JJ has taught several classes over there and as I understand it many of the locals have set up a UK DIR list..
As far as your specific questions go respecting doubles. You will route the primary hose off of your right port. This is done for several reasons. Primarily, you will donate the regulator that you are breathing in an OOA scenario. Accordingly, by donating the primary regulator you ensure that the diver that is OOA is gauranteed to receive a regulator known to be working at the time he needs it the most. When you start considering doubles it's important to start understanding that it's possible when inside a wreck or a cave that it's possible a diver will make contact with the ceiling and could possibly "roll-off" one of the valves. Given that the right [primary] port if it makes contact with the ceiling will "roll" in the "on" position, it's more beneficial to have the OOA diver on a regulator that even if you hit a ceiling will continue to donate air. Whereas if you juxtapose that against the left port, if you hit the ceiling the left port will "roll-off". Well, you as the donating diver in an OOA scenario, will be breathing off that port. If that should happen all you would need to do is reach back and turn your valve back on. If the OOA diver is breathing off that port and is in front of you, and you hit a ceiling you may not know that there is a roll-off until it's too late.
Hope that helps.
