I've found out some virginias, (not aged) which smoke somewhat harsh, mellow out in a calabash. Well aged VAs have a different personality,,,I pick up flavors I hadn't noticed before when I smoked them in a briar. Smoke the same blend side by side with a briar and check it out. I haven't folded and stuffed so I can't comment on that. Ribbon, shag, rubbed out flake, cubed ,,,all smoke dry and cool. I leave the aros to a cob, so I don't have an opinion on them.
As close as I get to an English blend is Presbyterian, so Lat bombs are someone elses territory to explore in a bash.
There's even a flavor difference between a calabash and a standard meer,,,so I've ruled out the meerschaum as the difference factor,,,must be in the space the gourd provides under the cup. I'm no expert, but I enjoy mine,,,have fun guys.
