There's your problem, the fact that its fully enclosed. It's of limited value fitting 6" ducting if there's at least not double the cross sectional area of a 6" duct. gaps les than about 3mm don't count - you need to open up an air entrance opposite the dust port so that the air flow can carry the dust away.

which to me begs the question -- if the blade is enclosed with a shroud, would you be better off using a low volume high pressure collector like a vac?

Yep,
However;
The shroud has to be completely air tight right up to the underside of the table to prevent dust escaping by the centrifugal action of the blade.
All of the shrouds I've seen have have had gaps around them usually to allow for the blade to tilt.
The centrifugal speed of the air (and hence dust) seems to outcompete the air speed the best vacs can generate around those gaps so dust escapes.
My TS had just such a shroud and I was forever having to removed the shroud to clean out slivers that a TS generates.
Eventually these slivers would block the smallish extraction port so I completely removed it.
With 6" extraction to the cabinet I have very few slivers to clear out and I can usually reach these by removing the blade and sticking my arm down through the throat plate gap and one of those springy pick up gizmos does the rest..
