Confirmation required for a couple of the nice Mr. Mayer's fiendish plots. 6 down. Clue: Failure to catch middle management stress (3,2). I have: R?B ?N. I thought RUB IN for STRESS but can't see the rest. Also, 20 down. Clue: Not all material is this desirable (1,4). I have: A-?I?T. I thought A-LIST for desirable but the rest is a puzzle. Help please.
