Sweet mainly, with just a little fruitiness mixed in. One warning -- the stuff is like Irish Blessing or Molto Dolce -- needs a LOT of drying to be able to keep the sucker lit. Have another bowlful of something to smoke while you're waiting!
To quote my dear old grandfather (more later elsewhere). "Right is right & wrong isn't." Is you is, or is you ain't, IOW.

This old boy obviously knew what he was doing, but mostly you shouldn't mess with even young gators. When they chomp down it's holy hell to get the jaws open. Don't want to mess with this old dude either!
Butane for me. I know letting a fluid lighter go for a few seconds lets some of the stench burn off, but I like being able to fire up ASAP. Used to go with matches at times, but I usually don't keep an ashtray handy.
I do get where mawnan is coming from. :) But customers do want to see what they're looking at before handling. Leaving it partially open for an extended period does weaken the springs/locks of course.
