My issue is they are pro Ms. If they're called them pro m plus or just the new stadiums if be fine with them.
Reasonable people don't think we can hit any legal utrip ball. We don't have teams trying to hit classic ws or stadiums regularly. We do have teams saying why are they hitting a pro m but I can't hit mine, and they're right! It shouldn't have ever been given the same "classification".
The wsl ball is fine if we're not going classic plus across the board below conference. That 44/400 isn't too hot in most temps, and isn't insanely dangerous in the cold. Drop the classic m completely, rename the hc, and go all pro Ms of a lesser variety of they don't have the balls to make the classic plus the across the board choice.
If they aren't making the classic plus the main ball, I would highly recommend calling it the classic league, and encouraging it's use for rec leagues around the country.
Here's what I'd do if I were USSSA. Ditch the hard core entirely or ditch the stadium. One or the other should go, and the ball that's kept should be used in stadiums. However, calling the hard core a Pro M is ludicrous. That ball does NOT perform like a .44 375 ball, and calling it one is asinine.
Ditch the classic M. Those balls suck, plain and simple. Too hard in the cold, and too mushy/dead in the heat. All using those balls does is encourage bat altering because the balls are so bad.
USSSA SHOULD go to C+ balls primarily, but they won't. IMO that would make for a more even, safer game overall.
If USSSA is going to keep the Pro M (and it looks like they are) they should allow only single layer covers.
For one year I'd like to see USSSA use a good C+ ball in Viera for worlds and see what happens. In heat/humidity C+ balls fly just fine.
I agree that USSSA should market a ball just for league, and that it should be a C+ (or something very similar). All the leagues around here use .52 300 balls, and no one has a problem with them.
