I have used different kinds of comb risers. The one I like the best is from Recoil Systems in the U.K., http://recoilsystems.com
I like it because it is very slender and does not add cast or cover a large area of wood below the comb. I love wood and hate to see more of it covered up than necessary. The comb riser is called the 'ISIS comb riser' on the Recoil Systems website.
