Looking at different types of blade’s from different OEM’s in particular ones like a mizuno mp 33, Titleist 680 or irons like that with a higher center of muscle my question is with technology so good now if you were to make a high muscle iron and put tungsten  bar or plugs at the very bottom back edge would that help launch the ball up in the air even with a high muscle blade not a cavity iron. Or Is that the reason why some of the muscle has lowered a bit over the years for easier launch just wondering
