Please remind me about VPI TT anti-skating.

I'm sure this has been touched on in older threads, but I can't seem to recall the answer.  I own a VPI Classic turntable with the anti-skating (AS) device.  I remember reading many threads which speak to whether AS is really needed on a VPI, .... in contrast to a gentle twist of the tonearm wire.  

In the old days, VPI (actually Harry) thought the twisted wire provided enough AS force.  Many others disagreed.

Well I went with the "many others" and through a couple of donut rings onto the AS device thinking I was doing good.  I got the feeling that the image balance seemed to shift to the left channel. When I disengaged the AS device, the image seemed to shift to the center of the sound stage. 

Does this make sense or would too much AS force shift the image to the right?  I am pretty sure that my tonearm wires are connected properly and the same regarding the I/Cs to the phono pre and from the phono pre to the linestage.       

I concede that if too much AS would augment the right channel, that the problem could well be the recording,... or maybe just my imagination.

Thanks
