I smoke a few times a week (2-3bowls, sometimes more). Each bowl is in a different pipe, no pipe gets two bowls in a row, there's at least a day in between pipes.
Great looking stores. Did I see a chess set (or some other game) in of the first pics? The two story one, wow! And love those adirondack chairs in the smoking lounge!
I unfortunately don't have anything even remotely close to what some of what you guys have :(
I try not to inhale while simultaneously smoking in order to prevent further inhaling into the lungs.
As for burn, don't think I've ever had it (that bad). Tongue bite? Plenty of times at the beginning. Learned to smoke slow, real quick.
Currently it's a toss up between Peterson Ebony Killarney 80s and a Donegal Rocky 106. Donegal was a gift/payment thing. The 80s was a treat to myself ;)
