Smokes better the more you smoke it in a day? My Peterson System 31 always seems to smoke better as the day goes on. Not that it ever smokes bad, but it seems to smoke drier and produce nicer smoke the more I smoke it in a day.
I usually only have two bowls max in a single pipe in a day and that's usually only when I have the time and don't want the smoke to end so I just clean the bowl and refill it.
