Executive Courses are all rated according to degree of difficulty (see golfthevillages.com site) on a scale of 1 to 4. Those rated the most difficult (4) are;
Amberwood
Belmont
Pelican
Roosevelt
Truman
I'd add Yankee Clipper to that list, if it were up to me.
They are all fun to play though,

I find it hard to pick one. A course that plays easy today is a real bitch tomorrow. It all depends on what player shows up on a given day. That is why I like/hate hem all!! :pepper2::cus::shrug:
