New Pipe Smoker With A Question? Ask an Old Fart

[jjmitchem]

I've got a couple of questions about pipe tobacco

#1. Where do the blends, the ones in the big glass jars in my B&M, come from? Can make note of the blend and find it at other places? Might be a dumb question but pipe tobacos seem a whole lot more complicated than cigars

#2. I like med to full cigars, mainly because I find the mild cigars to not have much flavor and all I taste is smoke. So far I have tried Carter Hall and Prince Albert in my MM Cobb and I really like that they both seem mild to me but still have great flavor- which is what I was hoping for- great flavor without the overload like a full bodied cigar.
What other types of pipe tobaco should I look to try?

#3. Aromatics - I love the smell of them but I have not smoked one yet. I don't like infused cigars like the acids so does that mean I will not like aromatics? Or are they completely different?
I was thinking about picking up a tin of CAO
