Tim,
Here is an attempt at a speed slot on a par 5. It is the second hole, Par 5 525 or so from the tips. The idea was to create multiple choices for the second shot (often a throwaway shot) and allow a "ramp" or slot that would allow a shorter hitter the chance to go for the green in two.
From the tee (I like this pic as it shows the back tee formed right off the back of a green high bunker on our first hole:
After a drive of 270 or so this is the view from 255.
You can (1) lay up down the right near a hazard all along the right side and this gives you this view:
or (2) lay up safe and left away from the hazard but be left with a mostly blind third:
or you can go for the green. From the fairway you aim between the single pine and the clump of three pines (see earlier pic above) and have to go right over the bunker whose lip is 37 yards short of the green. So, instead of having to bomb a second shot 255 to the middle (which is fine) a shorter scratch golfer faces a carry of 218 to just carry the bunker and find this 15-18 yard wide "chute" that will propel the ball right on the green:
Left is dead. A ball missed left is almost impossible to keep on the green with the chip. With the hole back right as in this pic, a great shot could keep the third shot close to that location:
Final view from behind the green showing speed slot and severity of green. The slope ties nicely into the green. Carry the bunker and it will funnel on the putting surface. A neat hole and a non-tee shot slot.
