"We've taken everything we've learned about Speed Pocket Technology and have been able to apply it into the face. Face Slot Technology provides greater consistency across the face, giving players improved performance on mis-hits. And you can only find Face Slots in RSi" - Tomo Bystedt, Director Product Creation, Iron, Putter, Wedge.
New Face Slot Technology in the 3-8 Irons:
Two slots located near the heel & toe of the clubface provides you with uniform flexion across the face. This ensures the protection of ball speed and generates a more consistent distance on off-centre hits.
Improved Speed Pockets in the 3-7 Irons:
Improved Speed Pockets with ThruSlot Technology in the 3-7 Irons provides you with ball speed protection on shots that are struck below the centre of the face and also increases the launch angle and ball speed on all of your shots.
