I think you need to get a separate baseplate to be able to mount other bindings on a SS board from that year. from what I have heard, it takes quite a bit of the flex out of the board though.
So basically I'm restricted to slingshot bindings with my 07 Response. That sucks. I love the board but the bindings don't last very long. I bought them new in May.
steve - contact Kyle with SS. he posts on here frequently. he has taken care of me on a warranty issue I had with my fins. I have seen him take care of other guys with warranty issues.
