Thanks to Vlad, a good one.
Took significantly longer than Prize norm, but short of an impalement.
Started slowly but a number of surprisingly (for Vlad) easy clues allowed some entry points. Had to frequently go into "Vlad mode", i.e. guess/solve first, parse somewhat/much later.
FOI 1 (which gave a false note of encouragement). LOI 12, which was easy to guess but took forever to parse.
Too many good clues to list right now, but 19 definitely COD. 21 also a standout, many more could be mentioned.
