39 is cheap... but what am I going to see? Ball motion? Watch balls hook? Arc? Skid Snap? Determine what layouts will do for some bowler? I would pay 10 times that if it was about me... providing me with the information that will guide me to understanding when and why a specific cover, or layout or core would be the right choice. I have been on this search for a long long time. I just don't get it. But, I am going to try to make this event.
