I have one pipe with a bowl that's probably about 2 1/2" deep. I like it, but it's a pain to keep lit. I've realized that packing it differently might help. Usually I gravity feed to the top, pack lightly, gravity feed to the top again, medium pack, gravity feed again and pack firmly. It seems like the tobacco at the bottom doesn't get packed enough with this deep bowl. So I've tried filling a little at a time and packing more firmly as I go - which seemed to help. Any other tips from you oom paul and chimney puffers out there? I read about someone doing two char lights in a very deep bowl and using a zippo...
