Gotta disagree with you re the Barnes example. I remember the shot well and that was just a case of an imaginative player playing the right shot, the only shot that had a chance of getting close. The same might be said for Davis Love III's incredible chip on #16 in the Masters a few years ago... up the slope way past the hole and back to the pin. Great shot, great imagination, but the only shot that could get close. So let's credit these guys for finding and executing the right shot, but not for hitting anything uncoventional.
In your picture, the uncoventional would be slamming a 4iron into the hill. Yes, sometimes that does work... but for all except those who practice that kind of thing, it is not the percentage play. In competition, under stress, it's very rarely wrong to make the percentage play...especially if it comes down to a shot one has hit thousands of times v. one that hasn't been practiced, like Pete says.
