Having played all of the top player's irons from Titleist and Mizuno over the past 18 years, these 502s are truly a cut above them all. I can't recall ever hitting an iron with better turf interaction than the 502s; they glide through the turf extremely quickly compared to other player's irons. The other key areas I've noticed a clear advantage with these irons are: less distance penalty on thin shots, look at address is very easy to line up, and excellent feedback. The overall forgiveness is shockingly good. Over the past 6 months playing these irons, I've had thin and heavy shots where the moment I struck the ball, I knew I just dumped 20% distance before even looking up, but then would look up and see the ball still in its good-shot window.
Simply amazing.
