Many thanks to Vlad for a delightful Prize challenge. He's becoming a favo(u)rite setter despite the slight feeling of intimidation his byline inspires. ;-)
On the difficult side, but not an outright impalement a la Enigmatist. Grid filled slowly but steadily. Feared DNF on the last few clues but pennies eventually dropped.
FOI 6.
LOI 20, though due to a corrected mistake in 19.
Too many clues gave pleasure to single out a COD.
17, 23, (8, 26), 13 and 20 stood out but others could be listed.
