I am somewhat fond of the McVinegar, myself.
I agree with roth that it is an instant cue that "this is McClelland" and you are in for a treat.
(Technically, this aroma can be found in other Virginias as it is a natural tobacco fermentation smell but few producers are able to capture this character in their blends like McClelland)
When I first opened up 5100, all I could think of was ketchup and I was afraid that the taste was going to be offputting.
I was quickly relieved and discovered that the sweet/sour/spicy/tangy flavours were quite charming.
Coalsmoke, I would wager that Beacon is incredibly light because to my taste Beacon Extra is not huge in the perique department. (Then again my taste buds only respond to brute force, with flavour bashing me over the head)
I would also suggest LBF over LNF if you are going the Stokkebye route. Just my opinion.
If there was only one Va/Per blend allowed on the planet, I'd want it to be Escudo. End of story. So that is my recommendation. Even if you don't think it will be a favourite, if you like Virginia Perique blends then you are doing yourself a disservice by avoiding Escudo on the basis of other people's reviews. It has a richness and intensity of flavour (at times) that none of the others can match.
Some think that it is over-hyped, but in the USA at least, it is fairly priced and readily available and widely reviewed so it is for a reason considered the gold standard IMO.
