I have just a few more Sutliff and Lane purchases to make to ensure my 12 year supply is guaranteed in my cellar. I can easily double the life expectancy of those tobacco blends by rotating other non associated blends into my smoking cycle. That said, if the products for my own time tested blends are no longer available, I may experiment with whole leaf- something I had been putting off because although I am curious, I am rather lazy about developing another learning curve to master another aspect of pipe smoking.
