I like most of the above, but i have to say I'm amazed how many blind shots have been nominated already. If you'd titled the thread, "The most epic approach shots are blind shots," probably 90% of people would have objected!
The most epic approach shot I've built is probably the 12th at Cape Kidnappers. The hole has been completely overshadowed by the 15th but the visuals are much more dramatic, and it is a scarier shot with everything falling away from the green.
