We're stepping a bit outside the perameters of discussing rules so someone may way push back - regardless.
Weather helm and balanced helm need to be separated for a minute.
Moving the center of effort fore or aft will induce a need to steer with either lee or weather helm, (in the sense that the tiller/rudder will need to offset the tendancy of the boat to want to fall off or steer to weather. A "balance" of the helm will determine the load on the helm but not the angle of attack of the rudder. By modifying your rudder you have balanced it but I'm guessing that in a 20k blow, with #1 and a full main trimmed in tight, you'd still have "weather" helm
I'm of the beleif that the helm should be pretty neutral and thus adjusting crew weight and sail trim (as in depowering the rig) is faster than sailing with "weather helm"
