OK, I am working up my next order and I am for sure picking up a bunch of 5100. I have been reading the descriptions of the other bulk blends. My question is this, any idea what the difference is between the 5000 series and 2000 series of bulk blends? I am just curious if there is something that seperates the two as two distinct different series or not. Anyone know? In their bulk tobacco, what other virginias are favorites? What about their bulk English/Balkans, what are some favorites? Any other McC bulk faves I should try? I know I love 5100 and will be adding more periodically until I get a few pounds of it put up for hard times.
