N.S.PRO Super Peening
 Steel shafts for irons
The N.S.PRO Super Peening model is another perennial favorite that ranks as one of golf's reigning "steel standards". Shot peening treatment strengthens the surface to eliminate shaft weakness and the resulting head lag. That means you can hit the ball hard and still count on accurate trajectories and greater control.
