I don't doubt that they have their charms. I used to see glimpses of their appeal but I was never converted.
Trust me, if they were cheap and easily accessible I would probably smoke them much more frequently.
If I could get a pouch of the stuff for $4 at the local gas bar whenever my heart desired, I'd probably learn to love them pretty fast.
As it stands, however, I find myself wanting a bit more of a flavour punch whenever I light up. (Which has become less and less frequent)
I also find myself susceptible to a certain type of OTC cottonmouth/aftertaste, probably from the PG or some other humectant. That keeps me from enjoying the experience a little bit and is not present with other blends.
I have never tried Carter Hall or Walnut but I am glad to see that you gents are finding some nice combinations.
The Middleton tobaccos are perfect for cellaring because their tubs and humectants retain freshness so well - they seem to be a good choice for stocking up if you like that sort of thing!
