I'd be happy if you asked him what he smokes for me. I stopped smoking a pipe half a year ago (earlier I was smoking cigs) and I sometimes miss that heavy, but quite good smelling smoke from the pipe.
I will next time I remember, but he's notorious for being hard to find when you want to ask him something. It looks ALMOST like this[1] but is larger. The cartridges are about like this[2] but the body is that thick all the way down. Given the fact that he's said before he goes through a cartridge a day I suspect he's gone and found whatever the largest capacity one there is, possibly from outside the US (at least I wouldn't put that past him).
