Note: I am a newb on CCR.
How does that help? It seems like if I'm doing a lot of up and down, that is what is going to burn through my dil - filling and dumping my wing. And loop - though, looking back I think I was mostly controlling my buoyancy with the wing
I'm running a separate drysuit inflation bottle. I pretty much always have helium in my dil, so I wouldn't normally use it for drysuit inflation.
You will appreciate removing dil from your inflation sequence when you use helium. Why would you pump helium into your wing only to then dump and refill your wing over and over. You seem to have made the connection to not waste expensive gas on inflating your drysuit, why not do the same for wing inflation. I too am new to CCR, more so than you, but the rig I choose played into my thoughts being pretty damn smart for a BM unit. Inflation for wing and suit is accomplished by an "inflation" bottle that normally rides in the spot of a dil bottle. Then I have the matching bottle of O2 on the other side. I sidemount my dil, so not only do I carry my bailout with me, I also have a huge amount of dil. I fill my bailout from empty with one expensive fill and then I just top off from there, simple and cheap.
EDIT : I will say that this may not be the best configuration for ALL diving nor would I proclaim it to be. This is designed specifically around cave diving, but with some tweaks the Fathom can also do sweet boat water dives. But, even in boat config you would not use your dil for inflation.
