Very interesting postings from our forum members. Always interesting to read through the formulas/recipes, and processing rituals that go into making a great smoke.
My approach, is to add small amounts of some other tobaccos, (or even small percentages of another mixture) to a "base" of a professionally mixed, bulk-blend, those blends that're easily available, economical, and well established. Making your own "hybrid blend" is a lot easier than blending from scratch. Just start with a professionally mixed blend e.g. "SWR", "CH" or what ever you enjoy smoking.... then tweak it with some other condimental tobaccos like Perique, Latakia, Dark Fired Burley, Cigar-leaf, etc. Just add small amounts, and write down the recipe(s) in a small log book. Keep track of your triumphs and failures.
In no time at all, you'll have your own personal blend, and the satisfaction of smoking something unique.
Good luck, and happy blending.
