Same here. 5 brothers is my go to additive when I want to smoke something around non smokers. I call my 1Q/5 bro mix "Brother Q" and my Night Cap mix "Brother Night". Straight 5bros is called "Daddy had a bad day"!What sort of blends are you looking for it trying to replicate?
Adding 1-Q or perique to blends is fairly common. Personally, I add Five Brothers to aromatics if in the mood for something stronger.
Then there are common copy cat recipes, like Hobbits Weed: 50% Lane BCA, 25% Sutliff Very Cherry, 25% Sutliff 1-M or Lane 1-Q.
