Hi, I’m using Textfugu + Wanikani and I’m progressing quite fast with kanji and vocabulary. The sequence is not the same, though, so you will end up studying some of them on Wanikani first, and then on Textfugu some lessons later. But still, I don’t see it as a problem. I also download the Anki cards from Textfugu and use them too (even though I don’t use Anki so much having Wanikani).
