Straight, high quality burleys took a while for me to come around to. I'm a VA person...not into perique, orientals, etc. The straighter the VA to me, the better, but some burleys give a good butt kicking effect that I had to get used to. Now I smoke quite a bit of C&D's #2 burley flake; they say it has a little VA in it, but I don't taste it frankly. Still not my go-to tobacco, but I certainly smoke it regularly now. Never "sat" on any like you indicated some do, just kept grinding through it to be honest (like scotch whiskey). Started coming around to it near the end of the first tin I ever tried, so it didn't take that long.
