If the one on RB carries the proper bailout, there should be no issue with gas supply.
I would think if this "issue" needs to be hashed out online, then someone didn't get adequately trained.
If set up properly it works fine. Through experience I have found it is important to have two sources of BO for CCR diving. One dedicated to the CCR diver and the other for anyone that might have an issue in the water. I have a short hose on a necklace that is easy for me to BO and get on and a long hose on the other cylinder that is easier to deploy than being OC with a looped long hose around the neck. The amount of gas carried by the CCR diver is very important as was already stated.
When I dive with a buddy with his RB, he carries two bailout bottles. The theory is one's mine, the other is his. I always tell him that in no way is his gas in my plans, but he still carries two. I think I understand his thinking, if he ever had to donate gas, with only one bail out bottle, he just lost his bail out, with two, he still has that option. It's either AL 40's or if deeper AL 72's
I make my buddies carry a buddy bottle, usually an AL80. I carry 2 bottles all the time anyways for my bailout. Self-rescue is my main thing when diving with OC divers. It isn't so much an issue when they are SM because of the redundancy, but it's better to be safe than sorry.
Problem is, a lot of agencies don't ever discuss this in training. I have to sit there and basically teach the OC diver a quick CCR class before we go diving.Quote:

I'd do essentially the opposite, on OC I'd dive the stages and leave the doubles alone. If it was going to be a 2 or 3 stage dive for me on OC I'd expect the CCR diver to bring about 66% of the gas I had in stages.Quote:

In a mixed team, I assume the OC diver will be the defining amount of gas or turn the dive first and carries the same Third gas as they would if the buddy was OC. The CCR diver carries twice that as bailout gas.

Consider this the start of my "adequate training". As someone who is getting into rebreathers, I'd like to hear ALL opinions on this issue and any other issue, get training on the subject, and then draw my own conclusions.Quote:

OC members need a brief understanding on what can go wrong on RB and what actions the CC diver will take. Also what actions OC diver can do to help.
Hope this helps.
