Welcome from central N.C. I've been to Dallas, to the convention center with the headstones on the lawn, where convention attendees tended to have lunch. I have some unusual wood for pipes, but I've become cautious. For example, currently PC is offering Stanwell's made of Beechwood; because they are Stawell retailed by PC, and are a carry-over from World War Two when pipe makers couldn't get briar, I'd say they have been field tested. I've always been a little wary of a little pipe hand carved of Cocobolo, though I think the hazard with that is the dust from making the pipe and not smoking it. I've learned to trust Mountain Laurel, but only made by a knowledgeable carver who knows which part of the bush to harvest. With so many excellent pipes made of briar, cob, and Meer, I don't think I'd branch out from those. Especially in briar and cob, you can get excellent pipes at moderate prices.
