Long irons are the hardest clubs in the bag to hit well, which is why TaylorMade engineers created the Rescue Mid, a breakthrough utility club designed to be easy-to-hit while delivering long-iron distance.
I own 3 of the 4 available models. I have been using the #3 hybrid for about 2.5 years. I have given up on my 3 and 4 irons and 5 wood. These clubs really help me on my approach shots. I made much better contacts which results in more straight and soft shots to the green. They help to lower my handicap by at least 5 shots
I still play 2 of these (19 and 22 w/Aldila NV85 Hybrid shafts) after 2.5 years. Every other club in my bag has come and gone at least twice since I bought these. I don't even think about trading them out. There still that good.
