Bought the RBZ irons from Taylormade last year. They offer more accurate/forgiving short irons and have "metal wood" technology in the longer irons for more distance.
I hit them against Ping g20s and Callaway razor, RBZ was the club for me. Gotta to try them and see what is best for you.
I personally love my RBZ, crisp feel, more distance, more accuracy, couldn't be happier.
I second the RBZ irons. They are so easy to hit and they gave me more distance too.
