Unfortunately Old Gowrie is actually a VaPer (check out the Kohlhase and Kopp website), but I think one of, if not the best VaPer around.
As well as Dark Birds Eye, Gawith and Hoggarth do a "Kendal Kentucky" (shag cut also) which is a 100% Virginia, albeit a fire-cured and African grown version of the "original Kentucky seed". I haven't tried the DBE but it sounds very similar to KK in strength i.e. VERY strong!!!
Gawith + Co also do their "Curly Cut". It's meant to be disc-cut (from ropes), but by the time mine arrived in the post, it was almost a shag / ribbon cut from transit. It's comprised of a dark-fired core with a bright-leaf wrapper, and I quite like it (again quite strong though!).
W.O. Larsen do a Dark Virginia called "Selected Blend No. 30" which is reputed to be like the old Dunhill Royal Yacht (I haven't tried the Dunhill so I can't comment), but tasty (and packs a punch) in its own right.
Surely there are loads of others from across the pond???
