from riding/racing fiddies a few times (I'm mostly a knee down guy as well) & watching the pro's (most notably the Jeff Wood/Doug Henry battle last year), it looks to me as though foot out gives you a higher entry & exit speed in the tight stuff, where knee down gives you more cornerspeed...

So I'd say give foot out a try in the really tight corners where entry & exit is more of a priority than outright cornerspeed.
