I am learning to write kanji as I learn to recognize them on Wanikani. One thing that really causes me trouble is radicals that are a little different in different kanji. Especially the radical ネ (“spirit”).

Does anyone have any tips for remembering which form goes with which kanji? Is there a pattern here? Or should I think of it as two different radicals?
