Al, I have a Jimmy Craig Ashton Billiard, and while it's aesthetically beautiful, it's not the greatest engineered pipe in my collection. If I'd known a bit more about pipes when I purchased it, I would have sent it back in, but being the beginner smoke that I was, I went ahead and smoked her. As it turns out, the draft hole is drilled off center by a more than a small amount and the top of the bowl isn't level. It smokes OKAY, but not well enough for the price a paid for it.
However, I have seen some beautifully carved, well-engineered pieces from Jimmy Craig. I guess I just got the one bad apple in the bunch.
And I agree with you on the 'clenchability,' if you will, of Ashtons. Mine has a saddle bit and it's one of my best pipes for clenching.
