Reading through these comments sure makes me feel better about my "rotating habits", or lack there of.
I'm not too big on the whole resting period idea.. I can understand why others would, and I'm sure as my collection grows everything will get more rest time.
I usually chuck 2 or 3 pipes in my bag for the day and a couple of different blends, usually alternating between those pipes each smoke (blend dependant) I'll probably have something dedicated to English, same for Virginia based, and pretty much always a cob too.
English's often come later in the day for me, so the cob or virginia pipe might get a few consecutive smokes earlier on.
Each one gets a couple of cleaners and a good wipe out right after I've smoked it, and i try to give it an hour or so before I hit it again.
If I've been going heavy on the same pipe(s) for a few days then ill give them a few days off too.
My new Mark Twain has been smoked at least 2-3 times a day since I got it earlier this week with no ill effects, so far its just improved with each smoke.
