I was just sitting here smoking Mac baren Roll Cake in my Trypis Billiard With twin bore system.
I started to get moister in the stem so I did the old pass the pipe cleaner thing through each hole and that seemed to work for a bit but it just kept happening.
I then decided I would stick the pipe cleaner in one hole and fold it so I could still smoke the pipe and this worked like a charm. With the twin bore stem if it gets moist ill just plug one side with a pipe cleaner and smoke and them alternate sides as it gets moist again.
This is of course only if it gets moist I don't see a reason to do this if your smoking dry.
