I've tried to explain the right hand drill / wrists moving up & down but he doesn't understand it.

By the way I believe the right hand drill and wrists only moving up and down is the BEST golf instruction I have ever seen. It as totally changed my game !
I am hitting the ball really well and so straight it's unreal ! Now we are getting some decent conditions, my scores are going down and I'm hitting more fairways and greens. Yesterday I had a gross 72 and that was in a better ball comp with me not concentrating on a couple of short putts that didn't matter.

I've mentioned the right hand drill to a few people and they look at me funny. Nobody seems to understand it. Yesterday, it was very windy and everybody else was driving it all over the place and I only missed one fairway !
