I never use a throw away word but I was so stumped that I started to put in unused letters on line 4. As soon as I put in the first two it dawned on me what the word was.
6 for me - If I hadn't done the throwaway on line 5 when I had 3 words possible, all good words, I would have had it in 5 b/c my gut word was right. But after missing last week, I didn't want 2 misses in a row.
