Tom,
Rick is correct. The slope for the 2nd shot on the 13th is an automatic left to right flight unless you are down near Rae's creek where it's level.
I'd have to choose the 15th as well. I've stood in the crosswalk of the 15th about 100 yds from the green, took several photos in each direction from there. I've sat many a lazy afternoon looking at the incoming shots - and I think you'd get the most bang for your buck on the 15th.
