I've never understood this crazy misconception and concern about the temperature of a flame from a butane lighter, match, Zippo lighter, etc. Well, that's aside from some of the insane 'torch' lighters that will burn through a freaking safe lock, but then again they are not intended for lighting a pipe. Can we all say haja... never mind. Anyway, I never apply the flame (whatever implement I'm using) directly to the tobacco, albeit I may do so quickly with the charring light. I simply draw the flame above and into the tobacco. Matches, butane, fluid lighters... all the same as long as you know how to properly use them, and that also coincides with with this 'taste' thing from butane and fluid lighters which I've never experienced. If done properly... not an issue. But, that's just my personal take on it and I've never had any issue whatsoever with using any source of lighting up a bowl.
