Handicap means very little towards what style irons you should play. If I had to place a number on it, I would say about a 4-5. Best way to determine if you should be playing them would be to go to the range with some impact tape on the face of your irons…

I like the idea of adding slope/rating. My home course has 2 18 hole courses to it. I'd like to be able to separate the and know which one I played on which day. Other than that, the feature is really good. 

Try Miz irons, got rid of my AP2 and went to the MP63, still love the 910D3 and 910F and PROV1x just did not like the AP2.
