Hey Jazlar, that's good to know. I hadn't realized 100% urethane balls were fairly close cousins to the reactive resin balls.
And I'm glad I'm not the only one seeing this behavior. I haven't seen an ASO bowling balls, but I've seen a fair number of Monster bowling balls roll down the lane. They're all quite rolly, and pretty continuous. I'd say the Monster pieces I've seen are a bit more rolly than the Global pieces. The Monster Kraken rolls at toes!
