I can't think of any time where passing the tank would be more beneficial than simply passing a long hose.
I wasn't comparing passing a tank to donating a long hose. I was simply stating that at some point after donating the hose, exiting the overhead environment back into the blue (also meaning once things have settled down) I MIGHT pass the tank off to the person that's currently breathing from it. Specifically once we're doing any decompression stops of any length I would possibly pass the tank off to the person just like I would a deco gas if someone had a failure of that gas and my use of that gas was complete, I pass that tank to them.
If you read my posts Rob, I am not recommending tank passing over long hose donation. This is why my first post on here clearly states that I have two long hoses and why. I was mearly stating that at SOME POINT after the OOG situation (after long hose deployment) that there can be a possibility for passing a tank. I agree with those who stated something along the line of making an already complex situation worse by passing bottles off....get a breathable reg in their mouth and GTFO.
