Using three equal parts, 2 parts Mac Baren HH Bold Kentucky, and one part Peterson Irish flake. Start off with one part of Bold Kentucky at the heel of a wide and deep chambered pipe for instance I found this parfait with a Neerup partial bent poker; then for the middle part use the Irish Flake, and the final part the other Bold Kentucky. If you're a fan of those tobaccos, in conjunction in this particular formula the tobaccos being burley, dark fire, perique, and Virginia all play well together in this sandwiched layering. For me I tend to get approximately three hours of pleasurable flavors and scents. It also provides an incredible room note.
