CH for me, whenever I can't make up my mind Carter Hall scratches the itch. However SG Best Brown Flake would be my second choice, not an everyday/all day kind of smoke which is why CH tops the list, but I love the flavour in the right pipe.
That's a tough one as my favorites always seem to change but one that I crave is GL Pease Ashbury with a close second being SPC Plum Pudding. Both are unique and delicious.
Just one pipe? That's harsh! It would have to be my Peterson Silver-mounted Straight Grain (sitter)#304. Not only is it beautiful to look at and a perfect smoker (as you would expect), but it is built to last my lifetime and many more.
Thanks everyone for conforming with this thread, I have very much enjoyed reading each and every post. So if anyone else would like to add more to this post please do, I will not over look any of your post.
