Despite the marketing prose, this blend has absolutely nothing to do with the original celebrated Bengal Slices except the can, which is identical between the two save for a little "aromatic" sticker on the corner.
Upon inspection, BSA appears to be composed primarily of bright virginias. The aroma is basically what you'd expect from a tin of a Virginia/Perique blend (both visually and nasally, initial impressions are that is McConnells Scottish Flake in a Bengal slices Tin).
Unlike most modern aromatics, this one doesn't have a heavily cased feel -- it does have a slightly sticky feel, but that's typical of slices. I'm not sure what the flavoring is -- I haven't yet smoked it with an audience around, but from the flavor contribution I suspect its some form of anise.
It rubs out easily and consistently, although the slices are very thin so if you rub it out too far you can get a very hot smoke indeed.
If the top layer is rubbed out very finely, it lights well and quickly forms a nice ash cap. The taste is about like you'd expect an aromatic virginia/perique blend to taste, sort of escudo with licorice, and it's really a shame that they ruined this tobacco with a casing.
Update: I just discovered that the flavoring is as persistent as Erinmore, after I smoked some Penzance in the pipe and it tasted exactly like Bengal Slices Aromatic. aargh!
