so i've heard that once you go forged, you never go back. im currently using tommy armour 845u's. is it true that forged irons wear down the heel a lot faster than regular steel? how bad is it? my swing is getting pretty consistant now, and i wanted to get fitted for clubs and i like and have read nothing but positive reviews for the mizuno mp-37's. thoughts? tips ? i will probably go with steel shafts, stiff most likely.
