I've never had BRM, but from what I've heard through the grapevine is that it's a pretty popular aromatic tobacco. Recently people have been stockpiling it because it was said to have been going out of production. However, I am not sure if that is true because I have seen it out of stock when it was said and then in stock again recently.
I'm not a huge aromatic smoker, probably 5 bowls a year, yet it sort of goes without saying that if you are primarily a non-aromatic smoker it might be hard to adjust your tastebuds for the sweeter blends and vice-versa. I find that when I smoke aromatics, I cannot pick up the flavors as well as I do with non-aro's. I don't think you missed anything, but with any tobacco, you might try smoking it everyday and the nuances will surely show themselves.
