Some babies can go four hours between feeds - DD fell into a regular, four hour feeding pattern at around 6mths. So we fell into FPS, but not through me actively trying, it just happened.

Basically that is because she has never fed to sleep - maybe twice in her whole life? We have been BF since birth and she is now 15mths. So feeding just before sleep never worked for us, it might have made her sleepy sometimes but most of the time it was (and still is) like a tonic that wakes her up!

I think you have to try a few things out and see what works for you and baby.
