I'm currently gaming KBS Tour S 120g steel shafts on my Taylormade Tour Preferred MC irons. I feel that on my longer irons, I have a higher trajectory than I would like. Everything I've read so far on the Project X's has said that they are lower trajectory with a more piercing ball flight. I wanted to see if anyone had any experience playing the Project X 6.0's and see what they thought. I usually hit about 170yards with my 7iron currently and I would like to keep that if I were to upgrade/switch to the PX's.
