I ride Flows and defend them when needed. They are solid well done bindings with better than average edge to edge performance.
I would look into M9se's, Fives, and Quattros. They're in order stiffest to softest. Though When I say stiffest, the M9se's are about a midlex park binding.
Fives are closer the Zero's. Those are a solid option if you want to just stick with traditional bindings and were going to be my choice for this year. Though I do also own this years M9se's.
That thing I do to escape the world and have fun with my friends
