I remember True Blue and Tobacco Road have some big movement, but 15' I doubt exists there as well.
Man, I really miss being able to play Tobacco Road as often as I once did. While I tend to talk crap about it, I really enjoy playing that place. I'd say #7 has 10 feet of elevation, and I'd say #8 has a bit more than that. Both of these changes are from the front, lower tier to the back tier. 16 also has a big tier, maybe 6 feet. I can't think of any more courses off hand that have big changes like that.
