Basic Layout... Need a Trackplan

After enlisting the help of the Nscale.net forums I've decided to arrange my 80 x 30" closet doors in an L shape, as opposed to an 80 x 60" or 160 x 30" shape. The 80 x 60 will make some areas of the layout almost inaccessible, especially if it is up against a wall, and the 160 x 30 would be over 13' long, making it hard to fit into my basement.

The advantage of the L shape is that it would make the entire layout easily viewable, plus it would make space for three visual focal points: two on the ends and one in the center. I'm going to place a city in the center of the L and two industries at either end.

Now the next question: What's the best trackplan for this layout? I'd like lots of mainline running (I'm neither rich nor experienced enough to put in lots of switches) with a few sidings. One suggestion I had for the 80 x 60" rectangle was a folded dogbone, which I would have liked, had I gone with that shape of layout. Is there any good way to lay a folded dogbone in the space I have available?
