I am currently playing with cally's Razr XL irons and as most golfers do, start looking at other equipment. I am interested in the AP1 irons but my friends say I would not see much improvement going from a cast iron to a cast iron. I am 55 years old and have been playing for about 5 years now. I recently shot my first 41 in 9 holes. I like the extra forgiveness in the cast irons but am curious if you think I would feel or see any difference in investing in the AP1 irons?
