Thank you, all! In fact I had "Bad Turn" as the answer to "Off spin is a nightmare to the user" It's obviously "Bad Trip", but spin=turn so the clue wasn't perfect!! Hence my "u" at the start of 6d and "n" at the start of 7d. But sorry to give you a "bad steer".
Actually, I still don't understand papaya, but |I'm sure it's right.
