The Terra Cotta King
If one has irons that are properly fit to them, one can all but eliminate heel and toe strikes. The goal is to get a setup that fitns one's repeatable swing in order to consistently strike the center of the club face. I don't care what iron head is on the end of the shaft, if you are consistently striking the middle of the clubface then it really doesn't matter. I suspect that if someone needs a little help getting the ball up, then a GI iron is beneficial.
Unfortunately, my swing is not perfectly repeatable, and I therefore do not hit the sweet spot in the center of the clubface everytime. If I did my handicap would be as low as yours big fella.
