Which board?

I'm having trouble finding the right board for me. I like smaller skim boards. I don't want something so slick I can't stand up on it and I don't want want something so sticky I can't break it loose. I also want something that I'm not constantly having to push to keep up(I know part has to do with the wave). Some boards on the same wave keep me in the pocket easier than others. I don't want to constantly work. I'm 5'9 180 pounds. I also don't want to spend more than $600-650 if possible. Thanks!
