Support fixture whips; 330.11 (D)2 or 300.11

[Finite10]

Which is superior; 330.11 (D)2 or 300.11 when supporting fixture whips?

300.11 says 'Cables and raceways shall not be supported by ceiling grids.
But 330.11(D)2 specificall addresses MC connectors as a support. BUT! Fixture whips are often not MC with MC connectors. They're listed 6 ft whips for fixtures, often.

Just wondering what the concensus if here.

If the whips are constructed from FMC then you can up to 6' unsupported.
