I'm not convinced that always making the center of lift in front of the center of gravity is the best idea. Placing the center of lift in front of the center of gravity makes the SSTO more maneuverable, which is good for slower speed SSTOs (which I think this SSTO will be), while placing the center of lift behind the center of gravity gives more control and aerodynamic stability (the center of lift [drag] tends to point retrograde from the center of mass) to the SSTO but possibly harder to maneuver and therefore control but not completely flip out. But then again, none of these "standards" could apply to this nonstandard SSTO. Just something to think about.
