Briar, Meer, Cob, Morta, Other? Not what your prefer, but what you actually smoke the most. I definitely smoke briar the most, then probably cobs and Mountain Laurel (I know a carver who does those), and then my one Meer. I have a clay pipe that I smoke only rarely. I really enjoy the cobs, the Meer, and the Mountain Laurel, but briar is my most smoked pipe material. How about you?
