Pros: Crisp, Pure, Great Feedback, Larger sweet spot than you'd think.
Cons: Not impressed with longer irons
First, I was fit for these on the Ping iN Flight System. Went through about an hour and a half fitting process. Learned alot about how I spin the ball. In the end I was fit for white dot and KBS Tour Steel Shafts +1/2" and I like pretty plain grips so I went with the Ping 703 Grip in Standard.
I was a 19 handicap before I got these. Dang near overnight, I went to a 10 handicap. Kudos to getting fit! The set came with 3i-U but I have since ordered the matching sand wedge with same set up and even got the matching serial number. Ping Rocks!
On the course the 7i thru Sandwedge is as good as it gets. Distance control is just about perfect. Sad to say, and it could just be me, but the 6i-3i just don't have the sweetspots that the rest of the set has. I pulled out my old Ping Zings in these irons just to see the difference and I still hit those particular irons better. I know...the Zings are shovels! Not really sure what to do on that. Hybrids? Maybe. A little age may have got the best of me on these clubs.
Overall, the look at address on the i20's IMHO blows away everything else out there. I just can't say enough about the distance control. 155 yds and in they are pinpoint.
Still thinking about reshafting with some Aerotech Steelfibers
