Stringeen, I have run with out any anti skate for several years. FWIW, my sample size in not large. Two ZYX Universe Carts and a Tri Planer VII and a TW Acustic 10.5. But the Tri is a 9" while the the TW is 10.5"-ish. But I use no anti skate with either. One would think that shorter arms might need that more? I have tired anti skate with both but could not dial in any thing that seemed to add to better sound. No anti skate sounded the best. With a 12" arm - why? Maybe I am missing something but this seems like another issue where there is a theoretical argument that is not always proved out in actual usage.
