When these first came out my brother and I (in our early 20s) both bought one and went to a center to try them out. We were just crushing with them, one strike after another, blowing the pins off the deck. Some kids on the pair next to us were just starting at us is disbelief. Great memories!
My highest averages were with the black Ninja and the original Zone. I threw 16 lb and those two balls elevated my game 30 pins higher than the urethanes I was throwing.
This is one of the best looking reactions I've seen you have in these vintage videos. It doesn't recover like a modern ball but otherwise it has a very modern reaction. It responds down lane with a predictable smooth arc that is continuous through the pin deck. It definitely looks like a reactive motion even if was a first generation ball. I assume that the Mo Pinel's core design goes a long way here.
