Bottom line is, a lot of people in here share your frustration with douchnozzles that swing glass but this is the 9000000000th thread about it. You are better off spending your time posting and searching in an attempt to learn all the ways to expose the cheaters and their shaved bats, guys around here will likely help you with that rather than flame you. Posting threads whining about how the douches in your rec league swing glass gets absolutely nothing done. 2 options,,, do something about it or stop whining about it.
I caught a team swinging glass in my league last year and instead of bitching about it, I came on here, asked how to expose a specific bat, lots of guys helped me out and the next week the team was fined and stripped of all of their wins, points and league tournament winnings.
