Hi. I have come down from 11 to 8 in a couple of months. All of a sudden I have started pulling the ball with mid/long irons.Think setup is ok but recently had sore back so might be affecting swing. Do you think this may be restricting/altering swing path through the ball creating more 'top half' at impact. Back is ok now but subconsciously might be protecting it a bit. As you can imagine this annoying coz I have played good stuff to get handicap down. Any ideas?
