As for brushes, most of the synthetics just don't quite work hair like a rice root, but they're better than not brushing at all. The rice root bristles are just right for really stimulating the hair and skin without irritating it, it's hard for synthetics to get that kind of consistency.
I use fluffer combs prob'ly 85% of the time. Regular ones on thinner hair, especially boning legs, wide tooths on really super thick hair maybe, but most people I know pretty much use fluffers for everything they used to use wide tooths for.
