you've said that to improve parity and thus increase participation they need small fields, rocks, rocket launchers and strict home run limits. This is literally what it is up to the highest level of USSSA excluding the smokey, dual and MWS.
Now you want fields smaller than 300-325 (standard for almost every tournament, shorter bases and mound?, and less lively bats?
And I while I missed the opportunity to play in the 90's I did start out by playing 3-4 nights a week in city leagues and 1 night a week at creeks. At that time there was still waiting lists to join the city leagues and Creeks was packed with only softball on every field through the 11:20 game. I never swung a composite until roughly 2013-2014, I still have a closet full of green bell corps and blue super cells I'm trying to burn through and love to take bp with.
