Niles, that sounds like a good idea. The problem with that IMO is umpires. It is hard enough for them to get two umps on the field all year long. Now you tell them there are different sets of rules for different leagues. Not a bad idea, just not probable in my opinion.
Whatever happened to the Chicago style slowpitch they were going to try in a league at Monroe? I believe that is where the ball is bigger, softer and the game is played without gloves.
