My coach and I have been working on the impact position for the last two months. I am making very slow progress it seems if I get the turn correct then my hands are late, I don't hold the lag or I swing over the top.. I have only been able to get one or two of these things correct at a time. I have been reading a lot of Kelvin Miyahira writings about the modern golf swing. He know his stuff but I have a hard time following all of what he is saying. He invented this tool to teach the impact position I ordered it and after twenty min. I seem to be getting it.
Has any body used it? if so post your results... I will practice with it for the next two weeks or so then post a video of my swing before and after.
