Thanks
@DrakeTheDiver. You have reiterated my own thoughts on the matter, and I appreciate the clarification on your ability to swap between your long hose and a shorter hose for your FFM.
I've often considered the fact that I've never understood the drills we run that have us doffing and donning our entire rig at depth. Now, this is a thing I can do in my BP/W setup, but no one else on our team dives with this configuration, so they are uncomfortable with the fact that there are no quick release buckles (though, I do share your concerns about plastic buckles).
I will have to explore some options for hose routing. I have already purchased a second regulator set for my team diving. Again, this is a personal preference because I, first, want to maintain a separation between personal and "work," and, second, I want to be able to have my personal gear out for service or drying after a fun dive or packed for my next fun dive without having to worry about the need to tear apart my kit or manhandle hoses if we have a call-out for a recovery.
That being said, because we don't dive with a mounted pony bottle, my largest complaint about my reg setup now is the stupid octopus, which doesn't seem to have a legitimate storage location on my current rig. Switching from my jacket-style BCD to a BP/W (which would be my preference) will only exacerbate that. I've thought about putting my backup on a long hose, but I have a concern about the FFM getting in the way of deploying that in an emergency OOA situation.
However, this is trying from the original topic of the thread, so I'll do my own thinking on that, but I appreciate the assurance that you do dive a single-piece webbing harness with a BP/W for your PSD work. That will make things easier for me to ditch my jacket-style BCD for something closer to my preferred (read: making me more comfortable in the water and, therefore, better able to do the job) way of diving.
