jchaplik- If you're looking for a caramel flavour I'd suggest the Royal Blend. I believe it's a Burley, Black Cavendish, Virginia leaf combination (the tin merely says "a blend of black and golden tobaccos). Almost everyone I've run across in reviews on youtube or tobaccoreviews.com mention the same flavours I noticed, that it tastes mostly like a caramel, vanilla, rum flavouring.
Jud- If you're looking to try one of the 7 Seas line, but you're looking to taste the tobacco more definately go with the Regular Blend. I've had the Black Blend, Royal Blend, and Regular Blend and out of them all the Regular is the only one that the leaf combination really came to the forefront. It's a Black Cavendish & Golden Burley leaf combination that has a casing of vanilla and chocolate. The casing didn't seem quite as heavy on this blend as it did on the others. Also this blend seemed to be the most complex of the three as the chocolate and vanilla flavours would intermingle and sometimes intertwine along with the Golden Burley and Black Cavendish occassionally taking center stage.
