After reading a few reviews, I'm going to pass. It concerned me how wildly different reviews were, mostly talking about the feel and forgiveness.
I'm pretty happy with the PRGR irons I'm currently using, but I've always loved having a couple sets, just to take out something different once in a while. I still feel a serious love for the Mizuno brand and there's something about seeing the little running bird across the room in my bag that still makes me feel like part of a big community. It's probably not a great reason to use a certain club in one's best interest, but I find a lot of fun in it.
Another set I looked at recently was some MP-H4 irons. I know more about them and have hit them before. With a soft flex senior graphite shaft, that could feel good... Just a thought...
And wait until you see the thread I'm about to start in the General category...
