I've had my AP3 iron for a few months now. I have started to see some great results from using them recently with yesterday being an exceptional day. currently a 14 hndcp but looking to improve. Not sure how much success was due to my swing or the clubs, but 4 birdies in 6 holes was intoxicating!!! 2 of them were less than 3 feet from the hole. I'm getting consistent yardages and great ball flight. Currently using KBS Tour-V shafts.
