Tom,
I'm not sure that shorter yardage is the secret to why MacDonald/Raynor courses are some of the most fun, since I think many of us on this website probably choose the 6500yd tees over the 7000yd tees on most of the courses we play. In that regard, we're comparing like distances. I think the template holes are fun for most of us on this site, but for the majority of golfers, it's the strategic, rather than the penal bunkering they consistently utilize. Combine that with boldly contoured greens, and I find myself walking off 18 wanting to head right back to number 1.
