Too bad. I was looking for it too.

Question: I find I can predict the ball flight better with impact fix address (bent right wrist at address) rather than standard address(flat right wrist at address).

With standard address my right wrist is flat and flexible and will become bent and fixed at the top of my swing. Then on the forward stroke I lose my alignment.

What do most prefer IF or SA?

IF for me. I've been doing it for years without knowing it was an "approved" method anywhere in the golfing world!
