Anti-skate problem with Rega RB303 tonearm

I like no anti-skate.  It's impossible to set it correctly anyway.  If you set it at any one point on the record the entire side before and beyond is wrong.Can anyone tell the difference with and without anti-skate? For the Rega problem, I'd check if the arm wire is binding, the cueing is touching, etc.

The cartridge is too light.   Try adding a minuscule amount of downward force and it won't mistrack.   I have listened both ways and like it with no adjustment for a/s.  Using a/s damps the cartridge to close in the sound slightly.   The whole thing is lots of talk with little benefit.  Im using an Ortofon cart for years, and the diamond is still in excellent shape.
