As a decent pool player myself, I couldn't help but agree with you. The game of pool/billiards should be played with a wooden cue. There is no reason why another player should have an advantage over me just because they have an aluminium cue. Billiards was originally played with a wooden cue - the tradition should be continued even in this day and age.
You don't see players of the MLB playing with aluminium baseball bats.
[edit]Added the word "see" in my second paragraph.[/edit]
Worst analogy ever. Aluminum bats can't be used, they were legislated out of the pro game for a lot of reasons and players would be using them if allowed. They're superior to wood in most ways. Graphite and aluminum cue sticks are legal and still not used by the overwhelming majority of better players, that alone should give you all the evidence you need that graphite and aluminum provide absolutely no competitive advantage. If you're getting your ass kicked by a guy with a non-wooden cue it's because he's better than you are.
15 years later, I wonder if he's changed his mind?
