Here's my review. I went out and played them, using multiple balls and dropping them at different yardages to learn the clubs. From a fitting standpoint, they are too light for me, My contact was a lot less consistent than with my normal irons. I tended to be thin, especially on the short irons.
Backspin the short irons was more variable than with my irons. This showed up into the wind as ballooning and inconsistent distances versus what I'm used to. I tried to knock one down, ehh, it sort of worked.
The 4 iron has bulge and roll, but it's the only one that does. I liked it off the tee and out of the rough. Never tried to hit a green with it. It doesn't fly high enough for me to do that anyway.
Impact is like hybrids, so not that solid feeling as from an iron. I never felt like I nutted one, but that might be more from the inconsistent contact. However, you don't have to nut them to get good results. Almost every half decent swing gets the ball up and fairly straight. I was hitting greens with them.
I think for an inconsistent striker, these will help a lot. I'm fairly consistent, just looking for more length and height. Overall they are not an improvement for me. I could play them and probably shoot the same, but I wouldn't enjoy the feeling.
