FWIW, I have a Wilson Benesch (also a Unipivot) and use anti-skate. My setting is calibrated using the HIFI News test record--there are 300hz test tracks with increasing amounts of gain. These induce distortion and you can hear if it favors one channel or the other. I find this to be a really effective way to properly set anti-skate, and the truest measure of stylus contact evenly against both sides of the groove.
