I will say that each time I play it, it doesn't SEEM like it should be that hard. I talked about how hard it was, and brought some good players to play it, and they didn't think it was THAT hard.
Seems like I usually play the second to back tees as well. I always think it is longer yardage wise from those tees than it really is. The holes that play long where length really helps are 6, 8, 9, 16, and 18, at least to me.
Now if you have a bad day off the tee, you can shoot numbers, for sure. But 90 seems REALLY high for you, with how straight you hit it..
