I hate FLOW bindings with a passion.
Tried them, and HAAATE them. I could never get them tight enough to give me the response I wanted.
I've started off on Burtons and they're a good all around binding.
Then I moved to Atomic Zombies, stiffer and good response, but the toe strap felt lacking.
Currently I'm running Flux Super Diamonds. Best of everything.
Stiff enough, good support, and response is amazing.
Absolutely adore them! Plus they look pimp!
