Thanks to all on GCA who responded to my request for suggestions on where to play in Jacksonville! Based upon all the posts and messages I received, we played Pablo Creek, a 14 year old course built by Fazio.
It really was a treat and unlike any course I have ever played in Florida. If you were dropped on this course, you'd guess you were on the Carolina coast, not Florida. It is cut out of pine trees, has significant marshland and a bit of elevation change.
You fast and firm guys would like it. Greens were very fast and putted really true. Quite hard, so you had to land short and roll the ball on (never my strength, so I struggled.) Definitely worth playing if you can get on this course!
