I have the 21 degree. Use it to replace my 4 iron. Had it extended 2 inches to get a good swing speed. I am 6'6" so itll let you know why I had to extend it.

Looking at gettin the 18 degree but I just picked up a Talormade R7 Draw Hybid thats 19 degrees. Would like to hit it for a while before I retire it to the golfbags hanging on the wall
