Forgive me if I'm being dense or missing something obvious, but I don't see how you can exhale into a bag when it's at arm's length (unless it is arm's length over your head, which I'm pretty sure is not what you're doing
).
To be able to exhale and have the gas go into the bag, the opening must be directly over the exhaust tee. If the bag is over the tee and the spool is at arm's length, then as far as I can see, the line has to be crossing your primary second stage. Maybe I am just having trouble visualizing it, since that's not how I do it.
Whenever I have orally inflated a bag, I always used a CC bag and held the bag and spool in the same hand (my left), with any excess line wound up. That way there is no line to catch on anything. After blowing a breath into the bag (actually a sausage), I stretch out the left hand (still holding both the bag and the spool), use the right hand to deploy the spool, and then let the bag go.
My preference is for everything to be at arm's length whenever possible, though.
I can almost guarantee that we won't be doing any diving in Atlanta - there's no decent place to dive here.
