How to use multiple hobonichi?

Hi, I'm pretty new to writing journal/schedule/tracking in general. I've been using hobonichi cousin avec for 1.5 years already as my journal and just started using weeks for tracking my health (sleep, medication, symptoms, etc) this year. I'm really tempted with this years' line up, and have already pre-ordered one (kanahei' hobonichi week). I plan to buy the suica weeks and tanakadaisuke one. I also like cousin because of it's size and the daily pages with calenders including Japan's national holiday (I'm living in Japan), but I don't really use it's weekly or monthly part, but I don't know a good replacement with similar quality papers and if I try original, but I'm worried I will not like the size, especially for journaling purpose as I write pretty long entries most of the time + adding some photos. Does anybody have ideas or experience on how to use 3 hobonichi weeks + one original/cousin and maybe how to use them fully? Am I just wasting money? Or maybe save it for next year? I really don't know what to do and I don't have anyone to talk to about this irl.

Sorry for rambling, and if my English is weird. English isn't my first language.
