From what I've heard you need to check out Middle. I've never been a fan of Eastern, it's flat, not that much excitement.
Devil's Glen is one of my favorites, lots of elevation, tight wooded shots, water, the whole package. The ONLY drawback of this course in some's eyes is that it's only 12 holes. Not a big deal to me.
In IL, I'd recomend playing Camden Park out in Milan. It's been around since 2000, and has had some changes since it's inception, but it's truly a great course with lots of different types of shots. It's kinda similar to Richmond Hill, from the shorts maybe a couple strokes more difficult.
I guess since I've never played Middle, my two favorites currently are Camden and DG. I have a feeling that will change next time I'm in town, though.
