Looking for a very light pair of snowboard bindings... advice?

Hi everyone. I am looking to buy a new pair of board bindings this year, to complete my board setup. just bought a forum substance, this years model, and am looking to make this a very light setup. i have 32 ultra light boots. I was looking at the new ride nitrane contrabands, whether its this years or last years, or maybe even the original contrabands. has any one had experiance with these or any other bindings that would fit the descrip?
