The Syn2 will be banned in ASA, starting Jan 1, 2008. It'll still be legal for use in Utrip/NSA/ISA play.
Warranty returns have to go back to the manufacturer, retailers won't take them.
The Mayhem is a good bat, I have 2, one for Utrip, one for ASA.
Mach1Nut, if you want to sell that Syn2, I'd go to Softballfans.com/forums and post it up. I don't know how much you paid for it, but since they're being banned the prices are taking a hit, I'd try quick.
