After almost a year of putting up with the chatter, I went to the Toyota dealership to get wiper inserts. The new inserts were back to being dead quiet starting from the very first wipe.
Compared to the Anco's, the OEM blades are ~1/8" shorter from backing plate to wiper contact edge, and this must make all the difference in this particular application. The slightly longer Anco wiping edge makes the blade grab and stick as it's moving over the windshield.
I continue to use Anco 31's in all other vehicles except this one, as I've never had the same chattering issue.
