The Callaway Rogue Pro irons share the features of the Rogue irons that give them their distance and forgiveness. However, the Rogue Pro irons have a thinner topline, less offset, and shorter blade length generally perferred by better players.
360° Face Cup and VFT Technology

The face of the Callaway Rogue Pro irons wraps around, forming a cup shape that flexes at impact, creating more ball speed and distance.
The face also has VFT technology, which stands for "Variable Face Thickness." As the name suggests, the face varies in thickness and is thinner around the outside. This feature creates more ball speed on mishits, so those shots won't be too heavily penalized.
Internal Standing Wave

A tungsten internal standing wave places the CG in the best location on each iron to deliver the ideal launch conditions to maximize performance.
Urethane Microspheres

Callaway put urethane microspheres behind the face to improve the feel of the Rogue Pro irons. The urethane reduces any vibrations for better sound and feel while maintaining ball speed.
