You will receive a complete custom iron set which will include the 4, 5, 6, 7, 8, 9, PW + FREE SW. The latest irons from Integra's PFT X9 Series Iron Set (Comparable to TaylorMade Burner Irons) feature a hollow core which is made from a two-piece construction and moves weight low and farther away from the hitting face to increase forgiveness. The insert face technology makes the hitting face more flexible, helping the ball jump off the club with high the ball speed wherever you hit it on the face. The more forgiving iron sole designs are wider in the longer irons to give you confidence, narrower in the shorter irons. The PFT X9 Series irons will give golfers improved performance with enhanced workability and forgiveness for ultimate confidence. The new PFT X9 Series Irons can make you up to 2 clubs longer - true story. It's the BALL SPEED all across the face that makes this distance a reality because for the first time ever, new Face Cup Technology that is used on fairways woods are now used on this iron set!
