My most common miss is a pull, (2 handicap, good short game) can do it with every club in the bag but worse with longer irons. I find that my hands tend to creep forward in my address position until they are at an impact position before I start the swing. Or they start at mid body and by the time my forward press finishes they are too far forward again. Could this be the cause of my pulls or do I need to look somewhere else?
