Q & A
Callaway's renowned 360 Face Cup technology uses a shallow, flexible rim around the face that flexes and releases when the ball is struck to boost ball speed. Variable Face Thickness uses thicker and thinner sections to protect that ball speed even on off-center hits. Together, they expand the portion of the face that delivers fast speed.
With the fast ball speed and increased distance of a thin, flexible face, sometimes you lose sound and feel to extra vibration. Urethane helps dampen the vibration but can reduce COR and ball speed. Callaway uses elastic-urethane microspheres to improve sound and feel without losing distance benefits.
Tungsten is twice as heavy as steel, allowing Callaway to use significant weight in a small space to precisely place the center of gravity in each iron. This provides optimal launch and control specific to each individual loft.
Rogue X irons are lighter in weight and longer in length with stronger lofts when compared to the Rogue standard. Wider soles pull the center of gravity low and deep for easy, high launch and longer carry distance. These are total distance irons.
