I shuddered briefly when I saw Mr. Ezersky's name on this grid, because he was the constructor of the final puzzle at the ACPT this year, and that seemed like a hard puzzle. But on the other hand, the winner finished it in less than five minutes, so...
Other missteps included "whistles" for REDCARDS (62A: Play stoppers), "juIceD" for ROIDED (45D: Used performance-enhancing substances, in slang), and "Sailor" for SEAMAN (1D: Salt).
I'm not sure I'm totally in love with BCHORD (47D: Group of notes reflecting a five-sharp scale) (clue too tortured), or SODACANS (1A: Tabs are kept on them) (clue trying too hard), but there's a ton of stuff that I do love in here. ABDUCT (6D: Shanghai), CUPOFTEA (9D: Personal interest, metaphorically), SLAY (33D: Kill it), BELABOR (40D: Go on and on about), PESTER (18A: Nag), ... and many others.
As for MASHNOTES (11D: Expressions of affection) and DOTCODOTUK (3D: Part of a London web address), well... I've learned a couple things today.
Overall, I enjoyed this quite a bit. I only wish CANO were clued with "Arma virumque ____." :)
