Rails

I shaping my first board and have some questions. I started with a 9’8"S blank and have cut a 9’6" 18.25"x23"x14"x3". I want noserider for summer east coast mushy waves. I have put a little concave in the nose and double concave around the fin area. My question is about rails. What would be a good rail for the board I have started? Also any suggetions on shaping the rails would be very much appreciated. BTW I am a 160lb intermediate surfer if that matters. Thanks in advance for any suggestions, I am really enjoying this site.
