For me last few weeks have followed the same pattern, a quick solve of the majority of the clues, but then the last few took the longest time. Not helped by incorrectly putting recoil as the answer to 1a. It was only when Davel pointed out that 2d is a hidden that I spotted my mistake on 1a
The parsing of 9a looks like a triple homonym, which is clever. I liked 16a. And always nice when the primary is an obscure answer like 6d. Let's see if everyman uses Lettish as a future answer to see if we were paying attention :-)
