The 920A can fill this void, just realize that due to the cover strength on this ball you will need to drill it fairly weak in order to get the reaction you are looking for on the condition you are intending to use it. I have a 2 different 920A's, but the one I have to fill a similiar void as what you are looking for has the pin about an inch above the fingers and a 1/4 left of the middle finger with the MB an inch and a half right of the thumb, and it still has a ridiculous down lane reaction at OOB surface. I use it for medium sport patterns once a hook spot is generated.
I have a similiarly drilled pin down 920A, almost a Mike Fagan special, which is fantastic on starting to open up long sport patterns.
