I go many ways on this issue; in fact, be warned for inconsistencies if not outright contradictions.
At times I really like smoking new tobaccos in a "wrong" pipe, i.e. one that isn't dedicated to the tobacco's particular type. The mystery of several flavors mixing is precisely the thing no other type of smoking can deliver. Honestly, an aromatic is only tolerable to me when smoked in a "Latakia" pipe. Then it has the essence and darkness I miss in aromatics.
Now, in contrast, a tobacco and pipe really do have to meet for a long time for all the nuances of a tobacco to develop. I'd argue that a blend isn't fully enjoyed until smoked a half-dozen times in the same pipe.
The third possibility is the compromise- in this case, keeping a near-type pipe. Like a VA, VA/Per pipe, an English/Balkan/Anything G.L. Pease (a joke, he seems to sneak Latakia into most of his blends) pipe, etc. This is my usual practice, as I've really only been smoking strong VAs lately.
My personal lineup consists of one Latakia-only pipe, 4 VA/VAPer, and 2 "whatevers" (mowing pipes, pocket pipes, etc.)
Thanks for the interesting thread, and the humor, too. I ain't afraid of no ghost, either!
Man, I like this site.
