Maybe you don't remember this - http://forums.azbilliards.com/showthread.php?t=100513&highlight=butt+rail
When I read it, I couldn't believe you were so adament about this subject. Many veteran players have a rhyme and reason for laying the butt end of the cue on the rail and it's not because they're trying to look cool. Also, it's not just break cues we're talking about. If the game is loser rack, then the racker is not usually walking up to the table with his break cue.
I'm not trying to bust your balls on this. I prefer to lay the butt on the rail but if others prefer something else, I'm not going to explain why my way is much better. I just don't care.
.... By the way, if it's loser racks why does he have his cue at the table anyway?
About 40 years ago in a game at Circus billiards in San Jose Ca I had just racked the ball and didn't get a chance to back away from the table when the cue ball came flying to the stack, went off the one ball and into my chin.
It hit my jaw square in the middle that I believe that is what kept my jaw from getting broken. I believe that if it had hit me to one side or the other it would have broken my jaw. I couldn't make a ball for a good while after that and developed a good size headache from that blow.
From then on whenever I play a stranger and don't know their mannerism I place my cue flat on the bed of the table in front of the rack and on the diagonal. Never mind protecting my cue it's my head I'm concerned with.
never put your cue stick in front of the rack and never lift the rack off the table if the breaker is aiming his shot. with the cue across the rack if he hits, the cue ball is going airborne right at you.
tell him to wait till you are away from the table. ive seen a few teeth go flying.
I've seen some dumba**es in my day, but I've never seen anyone stupid enough to break the balls when there was a cue stick laying across the middle of the table.
I guess some people can't wait to kick their butt kicked! j/k
