In my opinion, there are multiple accurate aiming systems that are 100%. It's how WE align to the visuals repeatedly correct on CB and OB with the eyes, head, feet, body, cue position, and stroke that can make any and ALL aiming systems work 100% or like a hack that rarely picks up a cue to play.Their isn’t a 100% accurate aiming system.
Have you tried two VISIBLE parts, like edge of CB to edge of OB? It's amazing how the edge of that white CB shows up so distinctly across the entire face from edge to edge on the colored OB. When it gets to a certain point, you can then use the other edge side of the CB.Everyones mind processes information differently. I’ve personally use different aiming systems on different shots. I’ve found the ghost ball to be extremely useless for me except on super thin shots.
