I fish them just like a lipless crankbait for my bassin. Lots of flicks and long rod lifts to get the massive amount of vibration they produce travelling through the water column. When I use them they vibrate so much that my wedding ring makes little clicking noises on my rod grip. Fast , slow, still. Mix it up.
Bass will hit any colour, I usually go for more natural colours though.
Last year I was partial to the Evergreen Littlemax in Ayu colour. Good amount of flash thrown off by this colour.
Last one I tied on was white which didn't seem to get much interest from the bass at North Pine.
I reckon these things would be killer on the flathead as well.
