Professional techie and amateur bowler here. I am bowling on old-ish lanes, and the stats we have beyond the score is... well, ball speed only and it barely works on half of the lanes only. I doubt that our alley would ever agree to install anything ad-hoc, but I am super interested in finding out more about your build. If you have a blog, or can post photos and some information about your build I would be glad to read more.

Good luck with your new business!!! It sounds super exciting, hope everything works out, the roof, the patrons, and all.

Perhaps with strategic striping on the ball they could also get angular velocity, could come up with some very cool stats. Or if you're really having fun, microchip every ball with an accelerometer / gyro
