Ahh, circles. Frannie dislikes them. I don't mind them, and today, as on Tuesday, the theme actualy helped me to finish the puzzle. So there's that. I'm not quite sure I know what a "Wood MAN" (43A: "Phew!"), but the rest of them are solid. I like the symmetry, I like the revealer right smack dab in the middle. Nice.
I tried "putt" for 1A: One may follow a long drive (CHIP), but the constructors obviously aren't the big drivers that I am... and speaking of sports, I was thinking about complaining about AROAR (18A: More than loud), but can't you almost hear Al Michaels using that word? I bet he has. Not that Al Michaels is, or should be, the arbiter of what is good fill and what isn't. Take SLATER (5D: Laborer on an old roof, maybe), for instance. He has also said that, but only when talking about Matthew Slater of the Patriots. It is not good fill as it is.
PREDATORY and it's clue "20A: Rapacious" are both good words, and I liked ORIGINALS (52A: Things often left at copy shops) too. I had "tASED" for 48D: Zapped, in a way, but StANG didn't seem at all a reasonable 47A: Dictionary label. It took me an inordinate amount of time to realize it was SLANG.
So, nice theme, some junk (KER, UNI, WAWAS...), but not too much. Decent Thursday.
