According to a chap I spoke to today.Let me explain this guy swears that when he's game starts to falter he switches to another set of irons he has and he's game picks up, when they stop working he switches back.And the claim is a fresh start resets the golf mind, he was actually a good player and told me he hovered around 16 for years and this system got him down to single figures.Now this may or may not work for everybody but its a good excuse to hunt for another set of clubs on ebay and try it!
