Purple Hammer Urethane (Purple Pin) Review | BrunsNick

An in-depth explainer review of one of the most controversial bowling balls ever made — Purple Hammer Urethane. I'll talk about the rule changes, why this change was necessary and a little bit of the backstory as I throw it out of box and compare it to my green pin version. For anyone reading this (who doesn't bowl on the PBA National Tour), your green pin Purple Hammer is 100% LEGAL to use in USBC and PBA Regional competition. The only exception were for those original batches with the serial number starting with the number 6 or 7. If you learned anything new about urethane, consider subscribing to the channel.
