Oh horrors! Conditions dictate how long a course plays at least as much as the number, so I don't know how 740 yards from an elevated tee plays in the desert.
To me it seems pretty simple... the best courses today are the same as the best courses 50 years ago and moving a tee on each hole back 100 yards! from where the average golfer plays (7700-6200 = 1500 / 18 is close to 100 yards on average per hole) means the trouble has to be placed on the sides. Where would you put a cross bunker?
John Fought and Tom Lehman are working on Windsong Farms, whose site is the old property of a doctor I caddied for. It'll be interesting to see how it turns out. Lehman's project with Kurt Sandness at Lake Jovita turned out very good.
This year's U.S. Open played at about 6900 yards on VERY firm fairways, so the course looked a little short on TV for them. But with par at 70 and other classic design features, it appears that Southern Hills is a place where the membership (98.3% of the rounds played this year by my estimation) and today's Touring professional (the other 1.7%) can both find enjoyment.
How'd you like to walk Fought's 7700 yard course if you played a forward tee? You might walk 100 yards past the back box to get to the "members" marker and another 40 to the "ladies" tee. Four hour round? I don't think you'd be close.
If John Fought set out to challenge me with a course of 6150 and par 70, I think it would be a lot more interesting than one of 7700 yards and par 72.
As mentioned on other posts, I do favor "flex" tees... the existence of a back box only designed to play when certain conditions (i.e. a lot of wind) necessitate that to preserve the intent of a hole.
Haven't seen Pumpkin Ridge but have heard it's nice. I'm sure I'd like some John Fought courses. But the assertion that courses need to be 7400 yards minimum, with a preferred 7700, only ensures that more courses will be built like the RTJ Trail. Haven't seen 'em, but my first choice would be Chicago Golf, Cypress Point, Merion, Cruden Bay, National Golf Links, Shinnecock, Royal Portrush, Machrihanish, etc...
