I thought about including actual clues for TALLY6DIn one's head[-----] and ACING1APosing a threat[-----], maybe with the clues for MENTALLY and MENACING in brackets, but maybe that would make the meta clues stand out too much?
really clever puzzle with just the right amount of sneakiness to it... i stared at ACING1APosing a threat[-----] the whole time since I didn't understand the clue and kept thinking AC was abbreviation for something I was unfamiliar with...
