Enjoyed this very much, have only been doing the listener for a year or so and I found this very elegant and fair. Inevitably, given the constraints, there are going to be (what I’d class as) non-words. On this there were only three that would never be used in educated conversation so that looks a very good rate to me.
The theme itself is a delight, one I’d never come across and dealt with in a nice way within the grid.
The two messages being repeated seems a bit odd to me but maybe, had Ifor used just one superfluous letter, it could have made the solve very much harder. Being able to cross-reference certainly helped this n00b get over the line.
Although Hit and Run appeared daunting at first with: no clue length, no indication of where each answer went and the doubly advertised ambiguity in the preamble. The solve itself was not overly demanding. (Yes I will admit to checking in here when stuck with a problem at the beginning.) Suspect I was also lucky in having the 4s done relatively quickly and jigsawing around the K.
A very delicate and comprehensive conclusion and, IMO, the 3rd best I’ve finished (after the brilliant Shut That Door! By Bandmaster and the extraordinarily elegant Difficulty by Chalicea).
