Okie-
I think we're talking aiming point. Aiming point on the planeline. I took for granted that we're on-plane, so closed is closed to the planeline. As you say, closed to the planeline will produce some kind of hook-spin.

I just say that, I don't think that an aiming point before the ball is needed because of the wish to hit up with the driver.

...and, I think there is some kind of relationship between launch-monitor numbers, the idea of hitting up and the need for open-faced drivers.
