That's why I jokingly mentioned the soakers earlier. Seriously, for urethane, softness is the important parameter. That's why softness, not age, should be the thing they measure and control. If they care about integrity (wow, guess I'm agreeing with Sean Rash), that's where their efforts should go. The USBC stupidly hung on to the static weight rule when basically everyone was throwing resin for years. If they plan on doing similar with urethane, there will be a lot of unhappy consumers. Of course there's no easy way to measure/enforce softness at the local level. And no one should care for most leagues, but their might be some belly aching at some big tournaments if they decide to do something about urethane at our level.
