Matt Ward,
I'd take Baltusrol Lower 9-1.
From the member's or regular back tees it's an interesting golf course, and I do believe that a good number of holes jump out at you.
# 2, # 3, # 4, # 9, # 11, # 12, # 13, # 15, # 16, # 17 and
# 18.
In addition, the green complexes and bunkering are superior to TN, although, I like many of those greens.
One of the comments I heard from a number of golfers was that there weren't any distinctive holes.
I'd disagree with that as I thought # 5, # 6, # 8 and # 16 were distinctive.
Forget about length at Baltusrol Lower.
Nonone plays from the tips and scores anything close to their handicap. The course from the tips is meant for one golfer, the PGA Tour Player.
But, from the regular back tees or the middle tees it's an interesting golf course.
If you compare the par 5's, par 3's and par 4's at both courses, I think you'd have to give the nod to BL.
In addition, since you're harping on the length added to BL, don't forget that TN is now at 7,560, which is far longer than BL.
