I have a 3/4 bent Ser Jacopo that used to smoke darker Virginias like gangbusters. It really brought out the low notes and deep sweetness. Three years ago, or so, I thought I would make it even better by sending it off to a reputable pipe repair business to open the airway. Additionally, I dropped the pipe and broke the stem tenon but, sent it off to the U.S. Ser Jacopo rep and had a new stem made-- this occurring well after the opening. The pipe doesn't smoke the same anymore and, as a matter of fact, is horrible. It no longer has the sensitivity it once had and any tobacco I now put in it is rather bland. It was this way before the stem broke so I think I can eliminate the new stem as any part of the problem. Has anyone else had a pipe opened up and it made it a bad smoker?
