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 wish I felt the same. I feel like I have to keep tightening my bindings all day, and if I'm doing a solid 9 to 4, by mid afternoon I can't find the sweet spot anymore. They are either too tight and cause foot pain, or too loose and not responsive enough.
