I purchased this ball 2nd hand. It’s basically new, the guy who had it injured his shoulder and can no longer bowl. I regret not getting the info out of him on how he had it drilled or if he was right or left handed, but it’s too late now. Was wondering if anyone here is able to tell if it was drilled for a righty or lefty 2-hander or if it doesn’t matter. The left hole is drilled slightly deeper, and the right is drilled slightly wider. Also should it be thrown pin up or pin down?
