2 pieces of advice:
1) There's more than one way to skin a cat.
2) It is up to the player to make sure he has the correct club.
The WGT caddies aren't the best in the world and often give you the wrong club. Once you have factored in wind, spin, the ball you're using, green speed, green elevation, etc, etc, etc, you will find that the caddie hasn't a clue what he is doing and you haven't a clue why you are paying him.
