The VPI arms are medium mass. Benz, Soundsmith, Dyna cartridges work the best. If you are getting mistracking on the inner part of the record, its not anti-skate, but cartridge misalignment, (Mint is great but you have to do it correctly....even though you spent lots of time on it, it still may not be right), or cartridge defect (worn, bent, old, etc.) Skating decreases with a smaller radius, and lower speed (the record is moving faster at the edge).
