I hear it's best to hire a cheap man--a man who doesn't amount to much, anyhow--who would be as well--or better--dead, and let him break in the pipe for you.
The leavings mixture is good. Starting from the bottom, I layered; LNF, SRT, Gaslight, then topped off with more LNF. The tobaccos are different enough that I could easily pick up the transitions. I'm burning thru the SRT layer now, wondering if I'll get to the bottom layer of LNF or if it will be too wet toward the bottom to burn.
-edit-
It got too wet. Just started picking up hints of the soft Va flavor of LNF and it got too wet and refused to burn.
