One thing I love about spigots and army mount pipes is that in the event of a gurgle, I can easily remove the stem mid-smoke and either swab it out or flick out the moisture in the same direction it came from and away from my mouth. Unfortunately, the very design of these mounts somewhat contributes to the accumulation of moisture, due to turbulence caused by the large amount of space in the mortise.
System pipes work, but I prefer the higher grade ones with a metal condenser.
Fun fact. The mortise, moisture well, and the shoulder for the shank cap of a Peterson System pipe are all fashioned simultaneously by a single bit on a lathe.
