This is a set of TaylorMade R bladez with stiff flex steel shafts 4 through pitching wedge and a Titleist vokey 52-degree gap wedge. There was 17.5 grams of weight redistributed to a lower more centralized CG location, promoting a higher launch angle, higher peak trajectory for softer landings. With progressive offset that promotes a square face at impact. The improved Inverted Cone design reduces directional dispersion for improved accuracy. With strong maraging stainless steel construction with a Speed Pocket that flexes and rebounds at impact to promote faster ball speed and a higher, stronger ball flight that lands on a steep descent angle. The Speed Pocket is filled with a Polyurethance Reactive (PUR) that keeps out debris and dampens unwanted vibration while still allowing the slot to flex at impact. PLEASE READ REVIEWS! You will love this golf club set! Original cost was $900, I'm asking only $325 or best offer.
