On a good day, it is whatever pipe I'm smoking. With 94 pipes or so, that covers a lot of ground. I have many personal treasures among my pipes, gifts, self-rewards, excellent cobs, surprise bargains that smoke as well as anything, and so on.
another vote for Peterson. My system spigot smokes great and has a slightly larger chamber. In fact everything about it from the hand feel to the way it smokes is just tops. It really seems to smoke everything great. Oh and it's a handsome devil too.
I have a number of great smoking pipes and some very rare “museum” pieces. But among my top five is a humble Brebbia Avanti that I picked up for a princely two bucks.
The fit is perfect, the draw is open and smooth, it smokes sweet, and almost anything I put in it really sings. It’s truly a magic pipe.
