IMO the ST Andrews course, although spectacular, is far too easy. It has no connection with reality, I bet today we will see a 25 (eagle on 5 and 9). St Andrews is a very demanding course because of the bounces on the greens, you must know exactly where to land the ball, so it rolls close to the pin otherwise you will find yourself out of the green or with a 200 ft putt. Generally speaking, I think the mechanics of the swing should be revised so that mis-hits are more penalized in terms of distance and direction, just like in real golf.
