The GP may be more aerodynamic, in which case it makes more sense up front. Also good to have the lowest RR tire (Turbo Cotton) on the rear because it bears more weight than the front.
But the GP also may have longer tread life, in which case it could make sense in the rear.
Your call on optimizing speed vs wear life.
