All great advice, but I'd like to add one more related tip for finding the enjoyment that comes from the bottom of the bowl. I find that along with too many relights (and perhaps the main culprit behind the need for relights to begin with) is over packing. Just like most things when it comes to pipe smoking, less is more, e.g. smoke slower than you think, less smoke on the exhale than you think and, in this case, packing less tobacco than you think. Packing less doesn't mean your bowl isn't full. Contrarily, you bowl is full; it just has more air than a tightly packed pipe. I've been using the swirl method these past few months, and the gravity/3pack method before that. Both methods promote the importance of an "airily" packed pipe.
Now the flavor profile of your tobacco will still change throughout the bowl; however it is a worthwhile metemorphosis. You will have a cooler more flavorful smoke with far less relights. But as with all things that come with our hobby, it takes practice.
