For me, it would have to be lead. The thought of a thirty pound cue just doesn't do it for me. Plus, you can't lick your cue, and I've already had to swear off of paint chips so I'm going to lick my cue. Of course, that was just a poor attempt at humor and seriously, I would also say purpleheart has never been a favorite. There are other things that I don't like in general on a cue, but then again, almost anything used in the right way can really work and look good. I suppose even purpleheart if used in a certain context could work well on a cue.
