For all you guys that use Zippo lighters on a regular basis: Do any of you guys have any trouble lighting the last bits of your pipe bowl with a Zippo, especially on your larger pipes? I have really started to like the reliability and the way that the Zippo lights when I need a lighter, but getting down to the bottom of some of my larger pipes has been met with mixed results. So do you guys have this problem, and if you have/had this problem, any tips or tricks to rectify the dilemma? Any advice would be appreciated.
