Yup, exact same thing happened to mine in the same spot. I'll be using mine so not too big of an issue! You might be better off with a 4U version as it'll be lighter for you if you're having problems with ZF. Otherwise it just wasn't meant to be! Sure I'll post again if my opinion vastly differs as I play with it! As of right now though, it's probably yonex's only successor to the AT700.
