I was thinking DG also except maybe R300. You could try both R300 and S300. As for the high fade, part of it is swing mechanics (slight outside in swing path) and maybe being a smidge flat on lie angle (probably about 1/2 degree). I have a couple AP1 irons with R300. S300 would give a little more control, a lower ball flight and a slight loss in distance (then again maybe not because you get more roll with a lower trajectory).

I would simply bend your irons 1 degree stronger and 2 degrees more upright from their current setting first. RC

Very good Idea as a first step. I am always Jumping the gun and not thinking about a viable solution. I am working on it though.

That's why You make the big bucks :)
