Like others have said you have to get something that works for you. I never quite got the hang of lineup cards I spent too much time wondering who was back row and for some reason I just couldn't see it quick. So I went to a lineup disk, and I love it! I am posting the link to it below. I have had several people say they tried it and didn't like it at all, then I have worked with a couple of other believers in the disk. Again you have to get what works for you, but this allows you to rotate the linup as the girls rotate and back row players always have the black color on the wheel so you can quickly determine if the girl hitting is front or back row. Again this is just one idea, you have to find what works for you.
