Dave, you gotta blue loctite the forward lean screw.
Ive used flows for years now & Ive never been able to use them as advertised. I step in, click the back & then ratchet the top straps down a little. To get out, I loosen the top ratchets a couple of clicks & then unclick the back. Once you get used to it, its faster than regular bindings, but like I said, Ive never been able to just set the top straps & just unclick the backs.... for me though, the Flows just hold my foot better than regular 2 strap bindings.
