I would like to hear what others think about this idea of having sunny side up on elbows.
If I could be specific. With your idea, at address, you would get into a position, in which you force the elbows close togther sunny side up.
This does seem logical. However,when you do that you twist the right hand up and to the right. At address, I want the right hand under and looking forward. I am still sunny side up with my right arm, but my elbow is more relaxed pointing down and a little back.
In fact, I think the easiest way to find this position is to bend the right elbow back (exaggerate it) at address (ball will go left), and keep doing less of that until ball goes straight, and you will find the right position.
My right arm and elbow is pretty soft at address, and there is a slight sense of elbow back, which allows my hand to grip up and under. My sunny side up (R) has a slight angle forwards. It doesn't face straight upwards like yours would.
I have to tune this in on each game, and it takes about four six iron shots to get it just right for that day.
It would be interesting to see what others think about this. I have gone both ways on this issue. I think this is a critical issue with the swing, and if you don't hit them dead straight everytime, this elbow issue could be the culprit.
