In "The Day of the Dove," intership beaming seemed like risky business. On the other hand, the incident involved beaming people, not bowling balls. I assume the safety requirements for beaming bowling balls aren't quite as stringent as those for beaming sentient life forms.
Your best reference for bowling alley data would be... a real bowling alley. I'm sure that a local bowling alley manager wouldn't look at you too
strangely if you were to bring a tape measure the next time you play.
