Getting a new set of irons: need input

[Cleveland Gunmetal]

Those were my final two. I went with the Mizuno's, should be here by Friday. Still not sure I made the right choice.

Callaway is great but you simply can't go wrong with a set of Mizuno irons. Good luck with them!

So...I had got with a club fitter today and hit some ping g5's. I had a lesson prior to this fitting, and hit my old MP-33's during the lesson. Once I started hitting the pings, they felt so bulky and clunky. I really think I want to stick with Mizuno's even if I have to work out some things in my swing. I think that the MP-60's may give me the benefits of the blade-like irons, with a little forgiveness thrown in there.

Any thoughts on that? (I am planning on hitting the Mizuno's in the coming week)

And with finding the right set of irons, I REALLY want to get the right shafts!
I am 6'4 and swing hard. I am trying to tone my swing down and get more tempo and make it more smooth. I guess I am looking at the Dynamic Gold s300, s400, and then the rifle shafts. (flighted..i guess?)

Any advice on the shaft selection would be great...
