For me, swinging feels like everything releases much later due to the automatic nature of the procedure. I don't get to both arms straight until well into follow through.
Actually, my feeling is that the right arm doesn't begin to straighten until after the ball. I must have been really messed up.
I agree that having more than one angel with you is good. Johnny Miller said he had three swings he could use: his own for a straight ball; Lee Trevino's for a fade; and, Chi Chi Rodriquez for a draw. He felt confident that one of those three would be playing good that day.
