Geo I've already explained that Flows don't hold you down any less than 2 strap. Its done differently and thus feels differently. If you don't like it that's fine but don't start giving "facts" about a binding that you never got set up right. They "feel" looser and you can dislike that all you want.
The people that choke their ankles are riding a strap that's too soft if they feel they need to tighten down that much to get the response they want. You should not have to do that. Flow's I-Strap is a stiffer breed but being that large and distributing the pressure better means you don't sacrifice the comfort for the strap response. So you don't have to choke down to get energy out of them.
