Kayak ramp materials?

I'm currently building a roof rack that has a winch and a ramp. I previously used pine boards for the ramp and I never really seen any damage caused by it. I was wonder if I could swap it out for one of those composite deck boards but I don't know how that will react. What's your feedback?
