Some old little known companies....
ASU made a urethane ball named the Patriot....had a rocket shaped core, looked like a Blue Hammer
Champions....small company started by Norm Duke, Del Ballard and 2 other PBA players....started with the Weapon series of balls.....Burgundy Weapon, Blue Weapon and Black Weapon. Then came the Ultimate Weapon and the Reactive Ultimate Weapon. Then came the Warhawk line and then the ultimate breaking up of the company. Yes, the balls were poured by Faball.
Pin Breaker had an interesting marketing strategy....sold their balls in 2-1/2 gallon plastic buckets, not boxes. Also they differentiated between their balls by coverstock and label color....all balls were called Pin Breakers
AMF had a great strategy with their AMForce line....numbered 1 thru 4, each had a different reaction and hook characteristic...
What ball was the furthest ahead of it's time?
The Track Shark wins this award.....this drill sheet for this ball made the Phantom drill sheets look like kindergarten reading material. I recall the pro shop I was using at the time telling me the Shark was the kind of ball that you wanted to give away and charge $200 to drill!!! FYI the core was designed by Mo Pinel.
Lots of others as well.....
