As I recall, the velocity is a relatively minor consideration -- it's
the altitude that helps Pegasus significantly.  (It might be different
if a hypersonic carrier aircraft were available, but none is.)

At least one study for a successor to the X-15 was figuring on using an
XB-70 launch.  This pretty much died when the second XB-70, the one of
choice for this job for some reason, got wiped out in a mid-air collision.
