I have got into the habit of taking a few puffs in quick succession, not just one sip, expelling the smoke from the opposite corner of my mouth as I take the next puff. Usually between three and four. "puff puff puff ... rest ... puff puff puff". I think I do this for two reasons, firstly, I can taste it better; second because it helps keep it lit are firing (I did just read Moo's post on keeping your pipe lit). Maybe this is a bad habit that is causing my smokes to burn to hot? I don't get tongue bite anymore, but I have noticed my bowls don't taste as good in the second half. The last quarter is often downright rotten, but I persist in order to properly break-in the pipe. What are the thoughts of the old-farts?
