I feel like Ian and I are on the same wavelength. Just last week, I was trying to convince a co-constructor to use HATERADE in a Sunday grid we're working on! Along with the colorful phrases HAIR OF THE DOG, STONE AGE, PAPER CUT, LINER NOTES, it made for such an enjoyable themeless solve.

Cluing was strong, too. LINER NOTES shined even further with such a deceptively innocent clue: [Statements for the record]. In this case, it was hinting at a vinyl record. [A, B, C, but not X, Y, Z] had me thinking about math, not a VITAMIN. People from Little Rock will appreciate the [Little rock] clue for PEBBLE.
And one of my favorite movie characters of all time, HAN SOLO, gets a quintessential quote: "Look, I ain't in this for the revolution, and I'm not in it for you, Princess." Who else could that possibly be? Granted, the writing is a bit hammy, but I'm a sucker for a great descriptive quote as a clue.
I always appreciate the care Ian takes to avoid gluey crossword bits. His themeless puzzles are so smooth, hardly a glob that makes me wince. Today, I did hitch at AGUE, a bit unusual for a Livengood puzzle, but Jim (Horne) and I had a discussion about AGUE where he argued that it's a fine piece of language seen often in historical writing. I'm not totally sold, but I can see his point.
With so many assets (I count roughly 13) and so few liabilities (maybe 0.5 apiece for AGUE and ESTER), Ian comes through with another POW! I like how he's always working with new grid patterns, whatever might fit around his choice of snazzy entries.
If there is anything, I'd like to see him push himself more, perhaps working with a lower word count, more long slots, stacks, whatever. Seems like he's more than conquered the 72-word themeless (the max number of words allowed).
