Jay,
Can't say that I agree with you re: the Lines of Charm. Especially on the holes out on the plane (starting with the 8th). The reason I am fighting for those angles is the hazards that create the line of charm. As a shorter hitting low handicapper, I play the back tees. On the Red, I am forced to cut corners on holes like 9, 10, 14 and 15 bringing the hazards into play as I chose. Unlike the Black, I can make my own trouble by making the hole longer and avoiding the hazards.
13 has one of the greatest central bunker complexes I've ever played, and it's a thrill to try and thread the needle down the left side in order to get the angle in.
I think your comments regarding lines of charm are more an indictment of maintenance than architecture. Every superior angle on the Red course is a fight, and the course makes you chose. The Black Course gives you some choices on holes like 4, 5, and 7 but for the most part the selection process is digital. On the fifth on the Black, I can avoid the bunker by going left to the little sliver of fairway, and then have little to no chance of a huge shot into the green. On 9 of the Red, I can bail right, and be tempted to lace a fairway wood on the green and get in a lot more trouble than I would hitting 6-iron - Wedge into the fifth hole of the Black. A smart golfer is forced to take Double Bogey out of the equation on the Black course, but is tempted to put it into the equation on the Red.
Similarly, your comments about length on the Red can be made about the Black as well. Holes like 10, 12, 15 and 16 on the black devolve into Driver - fairway wood - chip for a lot of people too. Or even worse... Driver, mid-iron, wedge...
Are you thinking of 16 as the right angle dogleg? 15 is the Flynn-esque par 4 that makes you play to the outside of the dogleg and the green is integrated with a fairway hazard from the Blue Course. 16 is the right angle par 5.
