The TaylorMade RSi 2 irons blend the company's best technology with great looks. By using a progressive multi-material set design these irons give you forgiveness and distance in the long irons, while focusing on feel and playability in the scoring irons. The 3-5 irons in the RSi 2 set have tungsten weights in the heel and toe to promote a higher launch and more forgiveness. The mid-irons have a strong steel face to promote faster ball speeds to boost distance. The short irons have a forged face while the wedges are fully forged from 1025 carbon steel to give you improved feel for better touch around the greens. These irons also feature TaylorMade's Speed Pocket and Face Slots that allow the face to flex uniformly when the ball is struck away from the center of the face. Whether you miss low, towards the heel, or towards the toe, ball speed will be retained. This means you don't lose distance on mis-hits, allowing you to hit more greens and, ultimately, shoot lower scores. The RSi 2 irons come stock with KBS Tour 105 shafts for high quality performance in a lighter shaft for consistent speed and accuracy.
