smoking, I would suggest looking at this pipe,in my opinion it will out smoke either of the two you are looking at and I believe it is in the same price range. http://www.smokingpipes.com/pipes/new/rad-davis/moreinfo.cfm?product_id=113416
My one Ashton has a great blast, smokes pretty well( not as dry as any of my Rads or other American artisan pipes) smokes very cool, but the stem design is not very good at all. The Ashtonite stem material to me is the same as any hard acrylic, and the button is not very comfortable. It is a nice pipe but I consider it a tier below all of my artisan pipes.
A new Dunhill might look nice, but in my experience( I own two and have owned two others that I sold off) it will not smoke as well as a Rad or other top American artisans. Just something to think about.
