So would I bend the hot metal 2 degrees to match the forged or would they then go to hi . I think they should of made them the same lofts then you could just make a set up like my old mph5s
Best answer I could offer is go test the irons in order to determine what adjustments if any would be required,
only you know your game and what distance, dispersion & high/mid/low ball flight you want to see in your game..!
I see by your Mizuno aviator you are based around the Bristol area so you are not that far from the Mizuno Performance Centre at Celtic Manor you could give them a call and explain what you are looking to do and maybe they could offer some advice and guidance to help you,
Maybe once you have talked to them you could go along and demo the irons and as its a Mizuno Performance Centre they should be able to adjust the lie & loft there and then..?.
