I have had a problem with swinging too hard and have really worked at it this year. I now swing my driver and mid to short irons (7 thru wedges)with a smooth controlled tempo and my shots are much less wild. I called it hit impulse. However, I still have a problem when I get to my 4, 5 and 6 irons. I swing back nice and easy and then just swing very hard from the transition going forward like a crazed madman which usually results in a hard low hook going half the distance I intended. Anyone else had this problem and if so, any tips to help me? Thanks!
