As far as far as the airfoils go the reason they are so deep is so that the diminishing angle is minimal, should be deeper more effective head on airfoils than any bike. You cant make a bike that is best at everything, this one uses super deep airfoils at the expense of catching more crosswind. You are correct saying Kamm tails would help this, but you are wrong on saying it is just as slippery. A Kamm tail is merely a compromise on a longer more optimized full airfoil and is NOT faster at discussed yaw.
This is not always the case - carefully designed, truncated airfoils can result in lower drag, even at zero yaw. on a properly designed Kammtail, the geometry forms smaller vortices on the blunt trailing edge that are shed quickly, which in turn can result in a lower Cd than the original airfoil. with yaw greater than zero, the delta between the truncated Kammtail and the original airfoil is even more pronounced.
