sdandrea1 I did notice that I hit my 30 degree G400 7i just as high as my 34 degree G10 7i, but 10 yards longer, and so on down the line.
I think this is where the potential benefit of "longer" irons comes into play. While some might say, "just hit your G10 6-iron," that would mean hitting a club with a longer shaft and lower trajectory. (So potentially giving up some accuracy.)
And say, for example, a golfer is playing G10s and the longest iron he has in the bag is a 4-iron because he didn't hit the 3-iron high enough. With the G400s he might find the 4-iron is still the longest iron he can elevate enough, but it's 10 yards longer. That's a real benefit if, unlike you, that golfer loses consistency or accuracy moving to a fairway wood or hybrid.
