We've all heard of the most improved student or athlete, the one who has made the most progress in stepping up their scholastic or athletic performance. What's your most improved pipe? Mostly, I have been satisfied or excited by the various pipes I've bought. Eight or ten I've traded away over the years because they weren't good smokers or had some other deficiency. Most pipes need some breaking in, so "improvement" is more than that. In my case, it was a Peterson rusticated slightly bent K&P author, never a bad smoker, but taking a long time to break in, and still not at the head of its class. But as time has gone on, it has firmed up and become a really good smoker, with a wide bowl with some depth, great for more complex blends. A far better pipe than it was for the first two or three years, noticeably. Never a clunker, but recently an especially good pipe. I'm not a cake-builder, keep the carbon layer very thin, so we're not talking cake building here. Anyway, what's your most improved pipe and why? And how?
