Sidewinder style counterlungs with BM doubles?

[Underwater Tourist]

I am curious what happens if the cave is narrow and makes an inverted V profile, so when you swim thru the restriction and contour the cave with your body, the arch on our back disappears, and you completely compress the CL so you cant breathe?

Or another scenario, swimming thru a narrow bedding plane, as you squeeze thru, can the ceiling of the cave press onto the tanks compressing them against your back and again making the sw/gemini unbreathable?

The sidewinder is a tool for a specific job. It can never breathe as well as some of the backmount stuff in all positions, ignoring its hose size and scrubber diameter, the counterlung is low and gonna inhale easy and exhale hard head up. Too much for me if I was in a scenario i had to work and not vegetate.

kinda the nature of the beast, had other ideas for it, had to rethink trying it…

The SW lungs are mostly at your side not on top of your back.
