I've not been smoking my pipe for quite a while, but here are a few favorites:

1/2 Sam Gawith's Full Virginia Flake, 1/2 Sam Gawith's Best Brown Flake

Rattray's Dark Fragrant

Esoterica Penzance

Presbyterian Mixture

Greg Pease's Caravan

Frog Morton (the original)

I also have a nice selection of Cornell and Diehl tobaccos. The "factory" is here in town and it is a real treat to have been given a behind the scenes tour. Exceedingly nice folks and great tobacco! Their Maltese Falcon is quite nice.
