One of my favorite types of backstop is one that is angled so you take your best advantage of it by being somewhere other than the hole's centerline. I really wish I had a few pictures to illustrate this but I'll try to explain. A newer course that's one of my favorites in the area has a hole that plays about 360, which climbs a very steep hill starting about 50 yards from the green, so you only see the top half of the pin (at best) from the fairway.
The green has two levels, with the left half being several feet higher than the right half. That bisection is angled so that the longer and further right you hit the ball the better it acts as a perfect backstop for a pin cut in the middle to middle center of the green. From the center of the fairway it isn't much help. The fairway widens to probably 60+ yards at this point to encourage people to discover this. Its a really nifty piece of local knowledge because you sure as heck can't see the two levels of the green from the fairway or the tee, so most people who aren't familiar with the course have no idea why I'm aiming so far right (even into the rough) when the pin is in a position where I can take advantage of it.
There's another fun backstop on that course's 13th, a very long par 5 of 565 into the prevailing wind that's also uphill at the very end. Its got a simply crazy green that even Doak might find pretty darn wild, and if you get caught out by the false front towards the left edge of the green you face an interesting little chip.
It looks for all the world like the ball runs downhill after you clear the false front, but it is actually pretty level there. There's a higher tier about 3-4 feet higher that lies behind it, which doesn't look it from that position but is actually so steep that you can use it to roll chips and putts back at the hole -- in fact, it is the only way other than a perfect (and highly risky!) cut flop to get the ball close from that spot! Very few golfers have the imagination to think of it, and usually learn about it by accident or watching me
The other fun thing about the green is that the false front is fed by a slope that extends pretty far out to the right, beyond the center of the (50 yard wide) green. There's a real John Kirk worthy moment when you hit a ball at a pin in the center and aren't sure if it quite had the distance because it can take 10-15 seconds after your ball lands on the green for it to gather enough speed to finally appear to where you can see it, and then another 10 seconds as it leaves the green before it finally stops rolling.
Someday I gotta go out to this course just after sunrise and take some pictures where the slopes really stand out. GCAers would love this course!
