Should I pick up wanikani again?

I don’t have all the answers exactly, but my suggestion would be if you want to spend more time on listening/speaking/conversational vocab rather than only kanji to consider something like unburn only vocab/kanji that you think you’ll want that you’ve forgotten.

Like if you’re using x resource on talking and they mention 挨拶(あいさつ) because greeting people is the start of conversations, you could go unburn that specifically.

You could also consider using Jitai because I’ve heard various complaints that it’s hard to read kanji that aren’t in wanikani’s font, so practicing multiple fonts will help.
