I often see players setting their cue on the end rail when racking the balls. That is, the butt end is resting up on the rail and the shaft is on the table. This is a big NO NO in my mind. And I know you see pros doing this too. DON'T!
It is so easy for something (like your arm) to jar the cue slightly and cause it to roll off the side of the table. Once it starts rolling, it's hard to stop. Even catching it is not a guarantee the shaft won't get nicked. And if it rolls off the side of the table, nicks on the shaft as it falls are a near certainty. The side rail will get your shaft on the way down.
Why not just set the entire cue on the bed of the table? It ain't going anywhere then. Maybe that just makes too much sense and doesn't look as cool. When I see players doing this, I want to scream at them, "You Frickin' Fool!" Once it happens and the shaft gets nicked, they usually quit doing this. It doesn't take much to get your cue rolling. Just a little nudge and it's headed for the side rail.
