A bit more of a mixed bag for me than, I think, for you, geeker. I found some of the clues a bit wordy and clunky, even though the solutions fell in nicely. 12d and 5a for example. But there are some nice clues, including those you’ve mentioned (though I also have quibbles about 20: ‘that is’ is necessary for the fodder but makes the clue read less than smoothly).
I did like 25: ab example of concision that I’d like to have seen more of.
And I’m afraid I never bother to seek out the Māori trademarks. Life’s too short.
Gosh I’m grumpy. Must be the heat.
I did sort of enjoy it though, and it was quick, which I needed tonight.
