One thing that is useful, for me, is to apply a touch of inside (TOI) while aiming the center of the shaft at the contact point on the OB for very thick cuts.
The small deflection of the CB makes it travel toward the OB a bit outside of the OB contact point that I am aiming at, and thus achieving the geometrically correct CB path for it to hit the OB contact point that sends it to the desired target/pocket.
If I employ TOI on a straight in shot, instead of center CB, with top, the CB will not follow the OB into the pocket and scratch. The CB instead veers away from the straight in line at a small angle allowing it to hit the rail and not scratch - cheating the pocket.
Again on a straight in shot, if I hit the CB center below it's equator, I can make the CB stop when it hits the OB, but if I employ TOI, the CB will travel a bit to the side instead of stopping which can be used to get shape for the next shot.
Observing what the CB does after impacting the OB with TOI, I notice that the CB reacts differently than if I use a center CB hit. This can be/is useful to get shape for the next shot.
Just saying and sharing.
