Well, nobody has accused The Thaiger of belonging to the brain trust of England, so quit killing my action
I think we are in agreement. Ghost ball is most def an aiming system, and one I would use for the novice. But for some folks they can't visualize the same as others. The more artsy types (wish I was one), basically folks that can draw portraits or anything, paint, or have good imaginations, can see the ghost ball from the get go, when others just can't see it. Thus, something else has to be used, something just as simple, like fractional aiming.
But bottom line, either helps them to see the shots and brain starts to remember them so they won't need to use them forever... kind of like training wheels for the brain
But yes, I would still bet on the aiming systems that are "above" ghost ball with two newbies, but certainly not something like CTE which is much to difficult for a new person to begin to understand. (for the record I don't use CTE but was trained on it so I'm familiar with it)
