Been shooting some rail shot drills and recently developed a problem that is leaving me baffled. Object ball frozen to rail one to two diamonds from pocket shooting between 25-35 degrees on most shots. The videos I've seen of high level players doing this usually has the cue ball hitting around the middle diamond on the short rail, then somewhere around the second diamond on the long rail opposite of the object ball. When I shoot the shot using high inside my cue ball path is more towards the opposite corner pocket or around the third diamond, and the first diamond in the long rail. I'm usually making the ball. Am I using the wrong spin to (more/less top and/or inside) or am I hitting the ball too thin or thick? 10:30 & 2:30 is about where I'm cueing.
