WhiteKnight is very good, but a totally different thing than 1Q. You will be facing a very latakia heavy blend that is accompanied by a lot of other Orientals that will give you a very incense-like smoke. All flavors that you get from WK will be pure tobacco, whereas 1Q has a vanilla topping added to give it, it's flavor.
WhiteKnight is a tobacco blended by our very Russ Ouellette from Hearth and Home tobaccos. It was designed to replicate the world famous Balkan Sobranie (which has changed over the years to not be as good as it used to be). So, he did a remix with this one to make it as close to the original as possible.
Balkan Sobranie is what gave the whole genre of Orientals the name "Balkan Blends." So, I hope you hand as much joy with that one as the 1Q.
I've never tried the 4th Generation blend you mentioned.
Enjoy!!!
