These oversized irons are great for golfers with slower swing speeds or those that have trouble getting the ball in the air. The 3-through 6-irons are replaced by i-Woods that are easier to hit than traditional long irons. The Center of Gravity, especially in the i-Woods, is lower to produce higher launch angles to get the ball in the air easier. The short irons have a hollow back and a large sweet spot for increased confidence on short approach shots.
