I have only seen one team using Worth, and I'm pretty confident they were using the Mutant. Lots of Demarini's, Easton's, some Louisville, and the magical Nike bats.
From what I've read, coaches took their business elsewhere for hotter bats. Maybe Worth reduced sponsorship, who knows.
As for RT, the only thing I have heard is that Anderson doesn't sponsor. Not sure if coaches would like the end-loading anyway.
