I just received a box of SJF a couple of weeks ago, and it seems to be a little drier than normal for Sam Gawith flakes. It only takes a couple of hours in the AZ dryness to get to optimal smokability, as opposed to 12-24 hrs for your typical FVF.
FWIW, if they started slicing these flakes thinner, I'd be all for that. I think one of the principal challenges for smoking Sam Gawith flakes is the preparation involved. I generally rub them out fully, but having the ability to fold and stuff would be nice too, and that's pretty much impossible for a thickly sliced flake.
To use a term that the OP used, while I do like the lady in my life to be "Thicc", I'll take nice and thin for my tobacco flakes, thank you very much.
