I would avoid any Flow bindings below the M9s. The Flites are a good introduction to Flow binding tech, but you'll be left wanting more. They are just entry level Flow bindings.
I don't jib at all so I can't tell you how they perform there. I do however do presses and butters on the slopes. My Flows do just fine. I ride the NXT-FSE. Great pair of bindings.
Curious, why are you interested in Flow bindings for jibbing? Is it the quick entry?
You have to keep in mind that Flow bindings feel different from traditional strap ones. It does take a little getting used to at first. The biggest benefit of Flows is the pressure points or lack thereof. I have virtually 0 foot fatigue when in my Flows. I have rode some very comfy traditional bindings, but they always give me some sort of foot pain after long sessions.
M9 or M9SE is good for a middle of the road price
NXT ATSE or FSE are even better.
