Well, to make a long story short... I don't do it. Through experience, I've found there to be no need to light, immediately tamp, then light again. I have sublime smokes, when I light, and smoke. I normally don't tamp until I've smoked nearly 1/4 of a full bowl- when the smoke becomes whispy and less flavorful. From then on, I rarely re-light, and tamp again between three and five times, almost always finishing a bowl with NO dottle. Any of you distinguished gentlemen follow suit?
