Thanks for all the info guys! Some of you are making it difficult to decide between a F and a J model. Just as you should! I know I've narrowed it down to the mid-length body since I want enough leg room for friends or if/when the kids need leg room in the future.
Here's an example of an F model that's nearby I can easily check out.
