Pat, I'm interested in the answer as well. I think the reversible course works well on a par 3 course. Another concept I'm interested in is the "kid's" course. Here I'm envisioning something about the length of a par 3 course, but with the design intent on beginners. So basically the length might be 1000-1200 yards, but it's not a "short course" by any means. 220 yards would be a true 3-shot par 5, 140 yards would be a medium length par 4 etc. If it were done with this in mind, I would think it would end up looking a lot different than a par 3 course with holes of the exact same length.
