I've played LBV, Eagle Pines, Osprey Ridge and Magnolia.
I would say that Osprey Ridge is the nicest course visually, and is a challenging course. For me, Magnolia is not as attractive a course to look at and is harder than Osprey.
That having been said, LBV and Eagle Pines are good also. LBV is nestled around DTD, Saratoga Springs and Old Key West so is quite interesting. Eagle Pines is very similar to Osprey Ridge to look at, but would give Osprey Ridge the nod just about. Just checked and I think Eagle Pines is now closed to make way for development.
