I've got a ball that's drilled 4x11 or thereabouts (if the "11" means the CG and not the MB). It's a pro-pin ball.
Also have a Girard layout, Tommy Jones layout, modified Tommy Jones and one where the pin is in the middle finger and CG in the ring finger.
Weirdest one I've seen but not owned was a guy in our league that has the pin of his ball on his VAL about 4-5 inches below the midline and CG under the middle finger. I don't even know what that's supposed to do.
