I don't know if he ever stuck with it, but some folks are familiar with a certain popular YouTuber (if you know, you know, but I don't want this to turn into a love'm/hate'm thread) who picked out a 16 blend rotation and bought 16 identical pipes which he then dedicated to each of his 16 blends.
It's interesting to think that if one were to have this level of dedication and discipline that there may be an actual advantage to it. Thanks for the replies!
It is interesting, because none of the people I know who dedicate pipes to a blends would ever consider doing it in this way. It makes absolutely no sense. Not all tobaccos smoke equally well in the same pipe, so why subject them to clones of the same pipe? Moreover, pipes are never identical, even if made from the same block of wood, by the same carver, at the same time. Greg Pease writes about this in his blog on PM.
This is more of a stunt, or at best a surrender, than a knowledgeable way of going about dedicating pipes. I have blends that offer up their best flavors in larger chambers and others that don't, but work well in moderate chambers. And while I don't dedicate a pipe to a specific blend, I do know which blends smoke better in which pipes, and limit the range of blends to those pipes. And I do have a couple of pipes that only get one blend. And, they are nothing alike, different sizes, different makers, different airway, different slot, all of which add to what happens, flavor-wise, when a blend is smoked.
Finding the best combination takes time and patience, of which I could use more. It isn't a cookie cutter solution, unless results really don't matter.
