The only problem you're going to have is the loft issue but that shouldn't be too bad. I went the other direction in lofts with my recent ho though and it completely screwed me up. I was trying to hit the 8-iron the same distance as my old 8-iron and when it came up short (as it should have with a stiffer shaft and 2* less loft) I just swung harder. By the time I saw the error in my ways it was too late.
The irons have been passed on to a new owner but unfortunately I still have all my old swing flaws that they brought back.
