I have since improved on a similar setup by using B5 notebooks with margins (to punch holes) and "filing stripes" [1]. It allows me to take notes of different kinds ("odd chicken scratchings of work notes") just by opening a new clean sheet (at a cost of occasionally wasting a clean page on the reverse side of a previous sheet) and then tear the sheets off and file them neatly (I use the stripes upside down so that an append "operation" is less costly). For long-running projects, I also use A5 notebooks that are pre-partitioned at a given % (I use 60-70%). The idea is that you go over your old notebook with "odd chicken scratchings", count the number of pages spent on each topic, calculate the ratios and multiply them by 70%*NUM_PaGES. Then you allocate this number of pages in the new (clean) notebook and put tab stickers on each section. I also leave around 4 pages for the TOC in the beginning of a notebook. It's just 2 sheets, but the ability to go back and put an extensive TOC later helps a lot when you refer to a finished notebook. With a bit of patience, you can but together a perfectly ordered TOC in a completely messy notebook (by doing one pass over all notes before writing down the TOC and grouping them by project). I also tried keeping notes on paper and writing down the TOC digitally in my Evernote to keep it searchable. Regarding spiral binding, I find it too flimsy. If you damage the spiral, flipping pages would cause damage to the pages. I prefer hardbound notebooks. I use fountain pens and previously used expensive paper but since the pandemic I tried Idena [2] and it simply blew me away with its high quality and ink resistance (except for some rare inks) at such a low cost (but I had to give up the dot grid). Ultimately, I am convinced that all of this has a limit and a Zettelkasten method of sorts is needed for a long-running knowledge base project.
