I had recently purchased these clubs and finally had a chance to get them out on a course to try them out. My typical score for my old clubs (Jazz Rockets) was 125, with these my last round was a 114 and I am pretty sure these clubs helped, though I will need a few more rounds to be sure. Most of my shots were off center towards the toe but I still managed to hit the ball straight with some good carry (170 yards with the 4 iron). I did have a couple errant shots where I sliced the ball but I attribute that to my inconsistent swing. So far I am enjoying these irons and they have definitely boosted my confidence when it comes to using them.
