And those instructors can teach what ever they want. What is your percentage of up and downs? I shot with nothing but green in front of you requires a different shot then say a shot over a green side bunker. It also requires a different club. You may have mastered your 60* but think if you had that mastery over every scoring club in your bag. It would be a no brainier. Use what ever gets the ball in the hole the fastest but you also have to be creative around the greens to get that done sometimes. I'm of the school that you need more than one wedge around the greens.
