I have used a number of lighters to light my pipes, but my two-penneth worth is this.
Normal Zippo's are OK but the Pipe Zippo's are better.
Matches are good, so long as you are indoors (or there is no wind around whatsoever). I have found that using matches outdoors, leads me into lighting my pipe before the match has burned off all that sulpher to ensure I get it lit. Sulpher, on your first draw is the absolute pits!
I then tried the double turbo-flame lighters (butane). Absolutely brilliant, these things you could use to weld with. They light your pipe in all kinds of wind, no problems. There are 2 downsides with a double as I see it. 1. you have to be very very precise with them, otherwise you seriously damage the bowl. 2. They use up butane like you would not believe.
My personal preference is a single, angled turbo-flame. You still have to be careful, but you have a little more leeway. They still use up a lot of butane, but not as much as the double.
