I got my i20's last Thursday. To be candid, I've really struggled making consistent contact with them. I seem to be hitting everything on the toe. I was comparing them to my old clubs and realized that they were a full inch shorter than my old clubs. My initial thought was that we either screwed up the fitting or someone messed up when they made them. I took them down to my local Golf Galaxy so I could compare the lengths to the standard black dots on the wall. Much to my astonishment, they were the exact same length. So now I'm thinking, WTF??? I happened to still have my old 5i & 7i's banging around my trunk so I ran out to get them for comparison. Turns out my old set was apparently +1" across the entire set. Moral of the story, I've been playing irons that are one inch longer than they should be for almost 15 years.
After two more buckets of balls and a round of golf I'm hitting the ball much better. I had to move what seemed uncomfortably close at first but now I'm getting used to feeling like I'm standing on top of the ball! I played my first full round last night and hit the ball MUCH better. The forgiveness of these irons is just stupid good. Shots hit square on the toe lose about 1/2 to 1 club length but stay relatively online. The CFS shafts are a fantastic improvement for me and any kind of a good swing is rewarded with a high but not ballooning ball flight. Of note, they also feel very soft. I've played essentially a forged blade for the last 15 years and I'm not disappointed with the PING feel. They also feel great and perform great around the green.
I'd recommend these clubs for anyone at any handicap level. I think these clubs are just all around solid. I'd HIGHLY recommend these clubs to anyone.
