Mox, are you crazy?

I'd much prefer the map/pin method, as you get a better idea of what you're shooting to - especially on a long skinny green. If it's in the back, you know that you generally have another 10 yards to go to the flag (past middle).

My course is even worse - red flag for the front half, yellow for the back. And the flag can be anywhere from 2 feet forward of center to the minimum distance from the fringe...
