Tom,
Most recent: Rawls. Ryan Mahaffey and I played at 6800yds if I remember correctly. The wind was nuts however. That affects my analysis greatly. #17 at 594yds was driver-7i if that gives you an idea.
Home course: Formerly Palmetto GC. I played a 50-50 split of red and white tees. Our reds are usually at 64-6500yds (and can be stretched for the Am to 6700), the whites at 6100-6200. I enjoyed the course equally at both yardages and honestly couldn't tell a huge difference score-wise in 30+ rounds over two years.
I do think that these questions are sort of moot though. I'd like to make a quick observation re: "reachability" at Streamsong on a course that was "unreachable" at 6698. Here's a hypothetical course: 6540yds (4 par 3's at 170, 10 par 4's at 390, 4 par 5's at 490). That course illustrates how "short" holes can be and still cause add up the yardage.
Let's try again on a hypothetical course. 6580yds (Par 3's at 125, 160, 180, 215..Par 4's at 310x2, 340x2, 390x2, 420x2, 460x2...Par 5's at 470, 490, 530, 570).
Only 40 yds difference in yardage, but some holes are uber short, some are uber long. No one is going to complain about the lengths of the holes on the first course. You going to get some whiners on the second hypothetical course, no doubt. They aren't going to be anle to reach up to 6 or so of those holes, but the course measures less than 6600yds!
This illustrates why total length--to me--is a measurement in ego and marketing acumen.
