Hello, I recently drilled up my old specail agent as a test ball for my new span, also I selected a unusual drill for it. It is drilled 6 x 4 ( thats pin under middle finger for me). My axis is 5 1/2 over 1/2 up. The X hole is drilled 4 3/4 over 1/2 down from my axis. It is 1" Dia, 3" deep. I bowl on wood for tournaments and synthetic for leagues. This ball reads really well on the cheetah and chameleon. Im looking for the same consistent ball reaction but, something stronger. Any suggestions
