Everything stated above me are pretty decent suggestions. And try them out as well. You'll learn as you go what method works the best for you. And once you find the niché, you stick with it.
Personal experiences:
My problem. I sometimes pack my bowls way too tight. Because I want it to give a nice tight draw. And yes, pre-light I've taken out the baccy and re-packed it sometimes with more or less in the bowl.
My tamping sucks. Just recently, I've learned to be gentle and it doesn't need to be pushed to a breaking point that it's too tight to the bottom of the bowl. I suffocate the baccy and get a terrible draw.
Re-lights...absolutely NOTHING wrong with multiple re-lights. I've done it 100 times probably in one bowl smoked. Some baccy's I packed perfect and had 1 re-light. Actually it was Goat Herder baccy gifted to me from Jeff (
@plumber1965). Smoked like a charm and like I said only 1 re-light after the initial light. The bowl I'm smoking right now...Piper's pleasure from Boswell's in my Nording Signature pipe. So far I've had 3 re-lights plus initial light.
Lastly, kick back with a drink of your choice and RELAX....
Oh and not bad for me suggesting things since I've only been piping 4 months, 7 pipes and a sh*t ton of baccy later....enabling bastids!!! LOL.
