Can anyone shed any light on why this would occur. Since making a few changes of late to my swing (understanding aiming point, my hands are finally ahead of the club at impact), I am hitting the ball great with my Driver/Woods (distances I could have only dreamed about before), most of my irons are pure (the occasional little block). But for some reason I am hitting shocking wedge shots from 90 in, they are usually really fat and heading right... Can anyone tell me some reasons why this would happen??
