Hate to say it, this ball did not work for me at all. Maybe it is the way my ball driller did the layout. He assumed it would "hook at my ankles" so the layout is very weak. The pin is 2 inches above my fingers, dead center between the two. The ball goes long and finishes late, very little movement. I tried dulling it and shining it. No success. My 811ASE has the same layout and it is great. This cover does not match up with my or maybe with the drilling layout. Might have to plug it and try something else.
