One of our older league bowlers ( 72 years  old ) recently had to drop down in weight due to surgery. He has rehabbed and is ready to move up to a 12 or 13 lb ball. I have heard that lane 1 has the best cores in their lighter balls. The ball will be used on a med. - med. Heavy oil pattern. What would be the best ball and does anyone have one with a span around 4 1/2 cut to cut or plugged, ready to drill that is around maybe 30 - 50 shipped to 28748 Asheville, nc??? Thanks, Ken
