The balance area of a rudder reduces the perceived load on the helm, but

Hmmm...seems to me that the steering torque on a rudder can be
reduced, zeroed or reversed - depending on the balance area fraction
selected. The rule of thumb, I seem to recall is 25% area forward for
minimal torque - more than that and the torque is reversed, giving
unpleasant positive feedback effect.
