Isn't torque only an issue due to bearing friction (and that's compensated for with engine mounting usually) and when accelerating/deccelerating the prop? I know the size of the prop and the power behind it can have a big effect obviously. Maybe it's just me, but when I took off in conventional twins by going full power, then brake release, it never seemed to take off to the left nearly as much as if I went full power while rolling.
