I went with the Futaba 3004 Servos also, except for throttle for which I used the 3003. With the Ailerons being independent, and each having there own servo I believe the 3004's should provide adequate service. It surely wouldn't hurt though in my opinion,that if you have a deep pocket that higher torque servos might provide longer service. It should be noted that I have not test flown this Plane yet, and it may prove that someone with a more agressive flying style than mine might indeed need the higher torque servos. This is just my opinions, and a person would probally best be served contacting VectorFlight, and finding out what they would recommend the most.
