It's a matter of personal preference really. I personally wouldn't put anything that soft on it, but I don't like soft bindings.
I just switched to the Flows a few weeks ago and it took me a run or two to get used to them. I've ridden stiff bindings all my life because I thought I had too. BUT after having the Flows now for almost a month I've fallen in love with them and would never go back. I'm just hoping they feel ok on this new board and I'm not getting loose and shifty everywhere.
