I get these typos because my eyes have moved on to other areas of the puzzle. I know it's OMERTA, not OMERTe, but there you go.
This is an amazing theme. I mean, just wow. Three phrases which contain in them a kind of belt, but which also have a terminal string of letters that make up their own word, and they each are 14 letters long. Then, to put the revealer into play, the answers loop around the back of the grid to finish on the other side, while also being split along the belt types? A true BELTLOOP? That's crazy stuff.
STOCKSCOL[L/AP]SE is the least standard of the three, but still it's completely acceptable. Meanwhile WOOLLYM[AM/MO]THS and PIMIEN[TOO/L]IVES are perfect as is. Hats off to Mr. Polin.
You all know what my complaint about this puzzle is: it's the hypersegmented corners. All four are nearly completely cut off from the rest of the puzzle. Still, the fill is so much fun, I don't really care. Look at those stacks: CRUCIBLE over CLEANAIR. YESSIREE. And ITSASECRET and HEDONISTIC? Great stuff.
There's also a ton of misleading cluing going on here. 60D: Works in a salon (ART). 43D: One living in the sticks, e.g. (NESTER - although I don't buy the answer, the clue is fun). How about 27D: One working for the lord (LIEGE) - note that lower case l in "lord". Dead giveaway, isn't it?
I could go on: I love the clue on OBAMA. 10D: Like records that are easily broken? (VINYL). Outstanding stuff.
1A: Tough-to-remove stain (STIGMA) - A+. Great clue, great word.
Fave: SKIM (1D: Less than 1%, say). I had no idea where this was going until I got KABOOM in place.
Least fave: TEDS (Spreads, as straw). Yeah. Huh?
