Agree. Equalising them is a good way to twist ropes.

Yep, and anyway you only need one rap station per route (or multiple routes), so is it really that important to skimp in the overall scheme of things?

I've previously imported SS hardware in bulk from a Taiwanese climbing equipment mfr, 23kN rated rings that look identical to the Fixe item. Freight on moderate quantities of metal is a killer.

My current preferred setup is a SS ring with a second backup using 8mm SS chain.
That way the second bolt can be a decent length away from the first hole (supposed to be 20cm according to Petzl), and the flexibility of the chain prevents rope twisting.
It also means you get a higher anchor-point to clip in with (on a second hanger or even through the chain, as 8mm is large enough to clip a biner). This is useful when approaching from above. If you get the lengths right it's virtually equalised, too.
