First of all, thanks so much for taking the time to answer our questions.
I recently purchased a set of Flow M9 bindings. I loosened the highback adjustment screws to move it back a little bit. However, after re-tightening the screws, they now all feel loose. I can actually slide the adjustment bracket back and forth even though the screws are tightened. Am I missing something simple here, or is it designed to tighten as you strap your boot in?
