I've seen (and recorded) a number of these old shows. I love watching to learn what some of these balls are. I didn't get into balls, until well after I returned to bowling in 1995.
One I saw 3 or 4 days ago had The Green Machine, Wayne Webb, become the Red Machine, wearing an Dyno-Thane XTC shirt and mow down a great field with 3 or 4 XTCs, all drilled differently, one with pin on axis was used for spares.

Just like hand grenades and horse shoes, in bowling you only have to get close ...
