Once the smoke enters the mouth the palate and its associated mechanisms, but more importantly the personality, shape it in many unmeasured/immeasurable ways such that it becomes quite impossible to describe any correspondence between the palates of said smoker and any other smoker's. Bowl geometry and drilling unique to a maker making the pipe smoke differently never made themselves known to me in my smoking, but I cannot contradict other smokers who make this claim.
Bur claims that a billiard with thick walls and a belge with the thin walls smoke differently, that long-stemmed pipes smoke cooler than short, are, to me, irredeemable bilge.
We have measured nothing in pipe smoking, not the influence of wall size, not the length of the stem, not the origin of the briar or the length of its cure, not clenching vs. hand-held, not the efficacy of sipping vs. huffing, not the rate of burn of the tobacco families or by cut. No, nothing. Yet on boards such as this we are free to say whatever has struck us, and it's great fun, but its in too many cases misleading.
I've done all of the above and no doubt will continue to do so. But I really don't know very much objectively, and I would put it to you that you don't, either.
