We all want a ball flight that we can control particularly when the wind is up. Callaway has upgraded its Apex hybrids from the previous model to include the latest Jailbreak technology. These hybrids make it easier to control the flight & to work the ball. These clubs are specifically designed for better players & tour pros. The club benefits from 2 steel jailbreak bars that add solidity to the clubhead which allows more impact load on the clubface for a faster ball speed. Faster ball speed equals more distance. The forged clubface is made from Carpenter 455 steel.
