Unusual strike in the 8th frame for Duke - ball hits the 1,3,5,6, and 9. 6 takes out the 10, 2 takes out the 8 and 4, and 4 gets 7 before the headpin can get there. slowmo replay at 0:43.
that was a badass ball too. And they were around at the start of synthetics and performed even better on those types of lanes. Columbia made great stuff back then. The U2 was a favorite as well.
