Briar isn't very absorbent at all... moisture penetrates to the depth of a few microns. Any built up cake will hold more moisture, but my pipes are usually dry enough to reload after several minutes.
Unless the air temp coming out of the tower is blast furnace hot I seriously doubt there will be any adverse effect.
All of you please refrain from getting excited by the following views. You've heard them before just as I have heard yours. Both of us have survived unscathed despite the airing of this difference. In all likelihood we will do so again.
In generaI I disagree with any agent save air at room temperature to affect a steady state to which to embark on the next smoke. And as the above points to an incredibly small amount of penetration by moisture, why the concern in the first place? And in general you need not worry about moisture though you smoke the same pipe continuously.
My touchstone in this is that both briar and tobacco are organic substances, and that briar should never be subject to flushing, as in the natural world only the life force protects the tree from degradation by water while the undergrowth of dead wood rots. Similar logic obtains in the case of tobacco subjected to the microwave, which to me is an affront to nature.
However assailed by scathing feedback to this post, I will not respond, because getting excited by words on a forum amounts to drama, which we all can do without. I'm not asking you not to respond but to respond without the drama.
