I just bought my first "artisan" pipe. From the outside it's beautiful, but upon inspection of the chamber it's obvious that the draft hole is way off center. It does line up with the stem as a pipe cleaner passes freely to the bowl. Should I be as disappointed as I am that It's not centered? Is this a shoddy job or perhaps a special technique to get the flow swirling? Not sure what to do about it... I would include a picture, but I'm not sure how.
