Thanks to all of those who provided helpful information.
Summary: ConsumerReports (behind a paywall) provides complementary test results. A summary of these is on helmets.org
The Venn diagram overlap between those favored by Consumer Reports (which includes high-impact performance) and VT (which is limited to low-impact concussion) is fairly small (and limited by a priori overlap of the two test sets). Those scoring well on both include:
Five Va Tech Stars and Excellent CR Impact protection:
•Bell Stratus MIPS
•Bontrager Charge WaveCel
•Bontrager Specter WaveCel
•Lazer Compact DLX MIPS
•Louis Garneau Raid MIPS
•Specialized Chamonix MIPS
That list is therefore artificially small, but if a helmet does appear, it was tested and it is favored by both.
