I think that's fair. In FRC it is generally acceptable that the velocity servo is oscillating (underdamped) by a few RPM above and below your target-velocity, and in exchange you get a fast response when target velocity changes, with no risk of integral-windup.

Just curious, did your team attempt a velocity servo and wasn't successful?
