I used to enjoy Balkan Sobranie back when Sobranie and later Gallaher blended it. I'm not sure what Germain's is putting in the tins they sell as Balkan Sobranie, but Balkan Sobranie it isn't. I've got a stack sitting because I can't stand this version. WhiteKnight is much closer to the original, and you don't get scalped for buying tin art.
Since I just picked up some 10 year aged yenidje at the WCPS, I may pop a tin and try adding it in to see if the stuff turns into something worth smoking. Balkan Sasieni is great!
