| Nigel,
You obviously feel strongly about this, not wanting to argue but heres my experience.
Its possible (they are being CE tested by the factory at the moment) to have rear lungs on the YBOD where:-
Theres no added dead space
You can still have a dump on the rear lung at the bottom for clearing and loop flushes
The water traps are the same
Clearing the scrubber is the same
O2 is injected not into the lung but into a adapter on the T
(on mine, dont know about the factory) With a BP and thin spacer you dont crush the lungs when inflating the wings
The only thing that you listed that you cant do so easily is cross arm flush - but theres other ways of doing a flush so not a big deal
Why bother?
Well OTS CL are great for WOB but very dangerous in my experience crawling through wrecks where they are exposed and I find they give a heck of a lot of drag when scootering.
I would post some pics but my computer got thrown across the workshop last week and Ive lost everything. I will see what I have at home. It is a neat conversion. I think you will see it common place within the next 3-4 years.
Cheers
