The Wilson ProStaff Fat Shaft Iron set has greater torque for more accuracy. Wilson also added a 3- and 4-hybrid to replace the hard-to-hit long irons. The hybrids have a graphite fat shaft, while the 5 iron through pitching wedge have a steel fat shaft with oversized heads for more forgiveness. The irons have stainless steel heads along with a wide sole and thick topline, which concentrates the weight toward the toe and assists the golfer in getting the ball up. The set is no longer in production, but can be found on the secondary market at several online golf shops.
