If anything the balance of probability is the spear tip planform @Blitzo proposed a while back. It's long enough to accommodate a large HCM, the planform is compatible with ELO, and it's capable of supersonic flight. The J-36 is cranked because of the maneuverability demands on a fighter and those are irrelevant to a bomber.Yes, the balance of probability is trending towards a double-delta, and away from a “super duper extreme ultimate LO” flying wing, or whatever the latest made up terms are.
