I think the current pin position is pretty well the most difficult one you're going to see on that hole. Anything on the back shelf (which is pretty flat) opens up a bailout zone behind the green and makes it more accessible. Right now anything on the back shelf or beyond is bogey territory or even worse.
I don't believe simply changing the pin positions is going to make a dent as far as leveling the playing the field is concerned. The best players in this game routinely fire darts that dance around the pin with scoring irons that don't roll out much, if at all. I'm afraid that changing the pin location changes only the distance of your approach shot and not much else. It still comes down to the ability to make the right club selections and execute consistently on the meter.
Also, not knowing the breaks around the hole doesn't matter much when you're putting from 6 ft or less 80% of the time. ;-)
