Really good points to concentrate on. I agree with you wholeheartedly that bad tempo and trying to kill the ball is the death of many a tee shot. And a repeatable preshot routine gets your mind and body in a good place to perform. Also agree that all but the best golfers should never hit a 3 iron, and 4 irons aren't much better. I myself have replaced those clubs with hybrids and it was probably the best equipment decision I ever made. As we speak, I'm thinking of ditching my 5iron for a 3rd hybrid too, they are that much easier to hit for me. Good luck with your round this week, but don't be frustrated if the score doesn't match your expectations... it may take some time.
