Solus Golf 420CS 3-Wedge Set Optimal Center of Gravity: Solus wedges contain a higher, more "rearward" center of gravity allowing for a better distance consistency and stability Pro Grind Heel: A camber has been added to the heel area of the crescent cut sole making it much easier to play the hard-to-hit, open face cut shots Perimeter Weighting: Full perimeter weighting helps to control distance and direction on off-center shots, making for a more consistent short game
