Interesting about the loose bindings. I myself have noticed that I like my binding straps to allow a little bit of give. When I overtighten a binding strap I feel a huge change in the way my board as a whole feels and within 20 feet, I stop and back it off a notch.
I was curious about this subject too. I know I've seen the subject come up on how newer riders tend to over compensate and tighten their bindings unnecessarily tight...does it make a scientific difference in performance how tight your bindings are, or is it purely preference? I get psyched out seeing my boots being able to wiggle in the bindings.
