Help! Ping G10 iron issues!!

Hi. Just an update as requested. I went to the fitting centre and tried a few things out.
As I am using ping g10 and it was a ping fitting centre obviously the choice of clubs were all pings!
It turns out that the clubs are fitted correctly, green dot and lie and loft, etc.... Tried some different models to see if anything could be improved.
Tried a g20 7 iron against my own g10 7 iron. No noticeable difference.
Tried a g20 light steel shaft....again, no difference.
Tried an i20 regular steel shaft, felt nicer to hit but no distance improvement.
Tried a g20 graphite shaft, hit it an extra 25 yards, but my bad shot seem to be exaggerated!

I was using the trackman system which showed up all my results from each club. It seems that my own g10 was by far the most consistent. I was getting a carry of about 135 on average and a roll of about an extra 7 yards. The g20 was hitting about 138 on average and a roll of about 3-4 yards. The g20 graphite shafts was on average about 153 with a 3-4 yard roll. But highly inconsistent(1 good shot out of 5).

So, it was suggested to me that whilst my swing and game has improved in the time I've been fitted previous and to now, that my irons are perfectly fine for me.
The whole experience and fitting process was really really good and I would highly recommend it. The software used was brilliant, and the choice of clubs(all be it ping!).

What now.... A couple of lessons I think!!

Peace of mind more than anything knowing my clubs are exactly what I need.
