I thought that anti-skate is always set by ear, you don't need no bloody test records, just listen. I am not familiar with the OP's set-up but with my Nottingham Spacedeck/Spacearm you can clearly hear the difference while moving the weight back and forth. It took me fifteen minutes and a few records to find the overall best setting and forget about it.
The idea that no anti-skating always sounds better is a complete BS.
