I don't know about the Shelter cartridge, but with my Goldring MM it took me some patience to set the anti-skate right. It was slightly better in one position with some music and slightly better in another with other music, but these were very small steps. With VTA set by ear I ended up with the arm in parallel but you have very different and heavier cartridge.
Yeah, Larry should be able to assist you in dialing it in if you need it.
