Thank you Greg. I'm using this layout to get back up to speed with 3rdPlanit. It's big enough to be fun while still being small enough to not be overwhelming.
I really like the wide open spaces and broad curves too. My only concern is that there is nothing else there. If you really want wide open vistas like that, and also want a big roundhouse, you may have to go back to considering two levels, there's not room for both.
