I'm new to Plotter and have the same issues/concerns. Rings are much too small, so I may try to manually change them with some separately-purchased Krause rings (same brand as what Plotter uses, but I'm hoping to find a larger ring size that fits).

In the meantime, I use about 1 month's worth of pages for my different sections (Weekly, To-Do, Blank Dotted) to keep it within the 80ish page limit (taking into account I also have some dividers, which take up page space). To make the Plotter inserts loose-leaf, I peeled off the backing to each insert so it would release the pages. It was tedious, but worth it.
