The half-graph half-lined page looks very cool, but I'd be concerned that it's not enough lines. I've dreamed of a half-graph-half-lined page on the left hand side and a fully lined page on the right hand side, but I don't believe that that exists.

I'm also unconvinced by the 24×36 squares form factor, but that's probably not a huge deal.

As to your main question, I think a ring binder is by far the best option, because it allows you to rearrange content you've created creating. If you're concerned about table space, you can just pull out the page you need. Also, you can use like Gary (pbuh) in picrel.
