I know this is outside of your budget, but if you could save an additional $150 (or sell some stuff), you might want to look at the Hammock Gear Cuben Fiber Tarp. The standard RL length is 11' with an option to go to 12'. Both are 8.5 ft. wide. Hex tarp (no doors) is $235 (5.2oz) and the Standard w/ Doors is $295 (6.5oz). I have the one with doors and couldn't be happier.
