The idea that you MUST change your current arm or anti-skate adjustment to get rid of inner groove distortion is just ridiculous. I and thousands of others with VPI unipivot arms have been doing just fine with them for a generation or more.
I use an old Shure test record that has a test for antiskating, the best available IMO. The Shure test records can be found at used record stores for a few dollars. My VPI arm with a "twist" passes the test perfectly.
There is obviously something very wrong with your setup that cannot be diagnosed at a distance.
