As for bindings in my opinion they matter the least out of any piece of equipment. I used to ride step in and baseless bindings, now I have some old bent metals with metal highbacks, wtf I know. They work and the don't ware out and they are stiff as hell with out being restrictive. Id rather spend my money on good boots or a new board.
I'm riding mostly backcountry so ill be on spark r&d binders most this year.
