Pipes made from block meerschaum tend to shift the flavor spectrum toward the cool, while briar tends toward the warm. Relative to briar, meer provides a highly detailed, almost clinical rendering, imo. With some blends this is great, others less so..but there's joy in the exploration.
No experience with that vendor, but I can say that IMP pipes are great values when they come up as estates.
@BE: aren't the Becklers made with a threaded tenon? If you have one, how's it smoke?
Oh, and PS: Meer pipes can and do ghost...don't let anyone tell you otherwise! The first mere I bought was a "lightly smoked" estate that someone trounced with middleton's cherry...worked on that thing for a year and I would still get a whip of cherry every now and again.
