i've got the saito .91 on mine and i think it's a great match. granted i don't fly above half throttle a lot of the time either, but there's also plenty of power to give you great vertical (for hammerheads, vertical rolls etc.) or to get you out of sticky situations. it also balanced perfectly without adding any weight with the .91 with rudder and elevator servos in the stock positions (i.e not in the tail). also, with a 16 oz. tank i've flown for 15-20 minutes and i'm not close to running out of gas. it'll definitely fly with the .72 (my instructor has that configuration), but to me it just begs for a .91!

p.s. i don't have a stick but i'd imagine the v60 would be slower due to the extra wing area and a thicker airfoil
