I put my Rocketbook into a disc bound system. Works like a charm. I've been using Rocketbook for a couple of years and haven't had problems with page curl or ghosting. I have had some issues with pens skipping or running out of ink quickly, but I've got pens I'm happy with now.

I would never recommend saving everything to OneNote, since there is no way to get information back out of OneNote. If OneNote was discontinued or you wanted to leave it for another reason, there is no way to export. The only thing you can do is to copy and paste, one note at a time.
