Callaway Rogue Hybrids are using Jailbreak & Hyper Speed Face Cup technology to create the ultimate hybrid. Callaway has managed to push the limits of technology & advances in manufacturing processes with a first for a hybrid to have Jailbreak technology. The Jailbreak technology was first seen in the drivers last year but Callaway decided to add it to their hybrids for extreme stability of the clubhead at impact, having two bars attached to the sole & crown of the clubhead stiffen the body of the club & restrict unwanted movement, so more energy is transferred back to the ball across more area of the club face for an effective boost of speed.
