Very interesting reading.
All I would add to that mentioned by others is be aware that your palette changes. More years ago than I care to remember, I smoked practically nothing but St Bruno. Easily found OTC blend in the UK. I always preferred the Flake to the Ready Rubbed, anyway... I believe that I nearly overdosed on the stuff and have avoided it at all costs for the last 20 years plus. However, I was gifted some "Home Brew" by a fellow UK Pipester and it was magnificent. Imagine my surprise when I discovered that the ingredients were,50% St Bruno,50% Condor Long Cut and a Pinch of Patagas Cigar leaf. Now both of those were on the "Avoid at all costs" list. Well I smoke them both on a regular basis now.
Same thing with some of the blends that seem to be bracketed as "Lakeland". I had mentioned that I wasn't very fond of anything Floral or Soapy, again, I was very pleasantly surprised when I recently tried some Ennerdale Flake, Bob's Chocolate and even another of our old standby OTC blends Erinmore.
I still enjoy a few Aromatics for a change of pace. But these tend to be edging more toward the subtle blends as opposed to something like Paladin Cherry. LOL.
All I am saying is this, don't make the same mistakes that we have all made before. We have all dismissed many an excellent blend, only to return to it and wonder how we had missed a gem the first time around.
