Something else to consider.
Since the PBA put a 2-year rolling ban on urethane now, the Purple Pearl Hammer is coming up on that, based on release date (May 2021). So they'll need to update and release the ball for it to stay current. We should start to expect this from Hammer every 2 years, let alone any other ball company that makes urethane pieces, as their release dates will be coming up on the ban as well.
