You can ride any style of binding both boat and cable. It's more a matter of personal preference. Some people prefer softer flexy bindings with greater freedom of movement, which makes it easier to do more tweaking on grabs and presses. Other people prefer stiffer bindings that will give you better power transfer with less loss of energy and will give more support to the ankles in keeping everything lined up and stable.
The Kais are good stiff bindings. If you want something really flexy, you would want the Parks or District bindings.
