Not sure information has been out long enough to get a good answer on this, but does anyone have a good idea what the differences are between the 'Boris and Sentinel and how those affect actual diving? (tough when virtually no one has dived a Sentinel, so I'll apologize for that in advance).

Differences I'm aware of:
-Boris two counter lungs, Sentinel one (what's the effective difference?)
Less dwell time with one CL
-Boris radial scrubber, Sentinel axial (what's the effective difference?)
Radial believed to be more efficiant

Does the Sentinel have the ability to take other sizes of tanks? YES Or do they go inside the cowling like an Inspiration? All the pics I've seen so far are cowling-less.

What material is the Sentinel cowling made of? I'm gonna guess it's not carbon fibre. Correct guess but neither is the Boris

Thanks in advance.
