I love all the speculation!
it's too big, it's too small....it'll taste nasty, metal gets hot... :rofl:
The pipes are quite variable, they can be cleaned and convection works both ways.
Here's what happens when you use those pipes with tobacco....it burns, you blow smoke and life is still good. Really guys.... :roll:
The interesting thing about pipes is how hide bound traditionalism masks itself as innovation. Overt innovation seems to have ended at the beginning of the last century and everyone else seems to be regurgitating the same design (more efficiently). I don't now of another hobby that is so static in this regard. Not that it's necessarily a bad thing, it's just odd.
Briar is fine, but so are plenty of other materials. Research and innovation here are essentially left to the hobbyist as industry has no vested interest in such. Just look at what's new these days. Plastic bowls with disposable clay filtering agents?
What this hobby needs is that one guy from shop class that would turn everything in to a pipe with a phd in engineering....
