I like these answers. Based on these, I think a good pipe, smoked properly of course, has the geometry dialed in just perfectly so that it does not create excess turbulence (and therefore condensation), and such that any moisture is perfectly metered out with each sip so that the moisture is not detected in the smoke, and after the smoke, there is no visible moisture in the pipe bowl, though some may be absorbed by the cake and wood.
Fortunately, only one of my pipes smokes wet, and I think I know now that it can be fixed. I will be sending it out and let you guys know if the repair worked. I'm certain now that the shank must be shortened to compensate for a mortise drilled too deep, the draw opened up a bit, and a completely new stem. Of course, I'm sure the expert will know better.
Sorry, I'm an engineer and probably think too much!
