The cf9 spryte is a -11The Spryte is a -12 bat that replaced the Vendetta. We did the same thing with the Vendetta. My daughter would use it against the faster pitching to try and increase her bat speed, but it never seemed to help. We never broke one, though. We would up giving them away to our local LL a few years back, and my daughter said she saw one last spring at the field when she was umpiring. I'm glad to see it didn't go to waste.
