Often I don't use any system to compensate for sidespin. I just know automatically where to compensate, and I line up on the shot that way, without really thinking about it. I guess it has alot to do with how used to my cue I am, because I am used to the deflection. I noticed that for alot of shots, the majority of the pros do the same thing. I don't see them pivoting their cues that often. Do any of you use sidespin without a system?
