Anti-skating on VPI arm?

I have a new VPI Aries 3 with a 3D arm.
The manual does not describe how to set the anti-skating.
In fact, it suggests not using it at all.
There is a filament line that leads from the arm, behind the VTA tower, to a counterweight lever.
I can't find a setup that works. The filament either rubs against the tower or the counterweight is not accessible or the line is too short.
Should I relocate the filament attachment ring behind the counterweight?
Anyone figured this out?
VPI doesen't believe in anti-skating. I don't have the exact same model that you do so I'm not sure what you mean with the filament. On mine, they say you can do a basic anti-skate adjustment by unplugging the tonearm cable, rotae it, and then plug it back in. Doing that puts some tension on the cable that acts as anti-skate. I tried it on mine, but it looked messed up, so I just put it back and left it alone. Keep in mind though, you have a better model than I do, so even though the design looks very similar, yours may have features that mine doesn't.
Trial and error for me. I'm not even sure if I have too much, too little or just the right amount of AS.

I'm using the Goldilocks method. When I send my cartridge to either Peter Ledermann or Andy Chong (sp?) for a stylus check, I'll ask if the stylus is wearing evenly. Based on the feedback I get, I'll adjust the AS.
I too have a 3D arm, and YOU JUST DON"T NEED IT. However, if you want to try anti-skate, the filament goes in FRONT of the counterweight, and just behind the black tower of the arm. I presume you know how to go from there, but if you have a question, let me know.
I use a first generation JMW-12. Never had a need for anti-skate even though it would probably not be much in a long arm. The tonearm leads provide just a little torsional resistance. Probably as much as is needed.
