You forgot to mention to be sure to use the recovery type cap if you do the overflow bottle thing. It has a gasket that keeps the coolant in the cap vent space if it fills. Otherwise you may get coolant spray in the engine compartment. John Hervey sells a stainless 15lb cap that is perfect for both that and the regular bottle set up.
