Yes, agreed on huge research holes.
I also like Kali's focus on dealing with lower-g forces through "softer" designs (LDL, dual density foam, less rigid visors, etc). And a company that stakes its identity on making helmets that protect you better from concussions, like Kali, is a company I'm way more inclined to trust in the face of research-holes uncertainty.
(That said, I personally have more faith in floating-shell designs like mips spherical than designs that rely on your head hitting the squishy thing like LDL or Turbines.)
My hunch has always been that, on balance, halfshells are better for reducing concussion risk during trail riding than fullfaces are. My theory being that wearing helmets that are lighter, have less leverage to whip your head, and cause a bit less fatigue will overall result in fewer concussions than ones that protect from chin-first hits. But the data to actually answer that question for mountain-biking doesn't exist to my knowledge.
