But the characters don't stick in my memory that well when I practice them separately as opposed to writing whole example sentences.
Yeah, that makes sense. (When I was first studying Japanese I lived in a college dorm where the hallway walls were white tile, so I used to write the characters all over the walls with erasable marker...End result, I read fluently and write like an 8-year-old.)

(And thanks again for the Anki-with-real-voices! I love it.)
