The course I referenced in the initial post is Idle Hour, a Ross design in Lexington, KY. Their head pro, Pete Garvey, posts here occassionally.
Mac, I think you're onto something with hazard placement. I found Idle Hour's hazards dared you to make aggressive plays off the tee, but there were routes to avoid them as well. I've played a lot of "tough" courses that don't require a lot of engagement on tee shots - just line up and hit it straight. It's nice to choose how much risk you're willing to take on.
Also, for whatever reason, I find that when I hit shots with a purpose (carry the bunker, bounce off the kickplate and feed toward the pin, etc) instead of just a stock swing to a target, I tend to hit the shot where I want more frequently. I don't always make the carry and the kickplate doesn't always feed like I pictured, but I don't usually miss my target by fifty yards like I do so frequently when I just aim down the middle. A tough course with a lot of purpose-filled shots often leads to a good ballstriking day for me, and that might be part of why I loved Erin Hills and Idle Hour so much.
