I personally think the Global West approach is a better one, poly 'squirms', and at speed on a sweeping turn will allow more oscillation then the sphericals. As for the front uppers, they move around alot, especially under hard breaking. If you've got a pair on a car, look at the bushing and you'll see where it slides to and from. If you want a pair of the hotchkis uppers for a 68-72, for the f-body spindle, I'll sell some cheap. I have 2 pair...
