Very good comparison review.
I too have shot the Grizzly 185's and the Kodiak 235's exclusively for many years now, even before I'd even heard of Dr Ashby's and his studies.
The 235 grain Kodiaks have been a great Buffalo and pig broadhead, and the 185's work great on deer and goats too. All have been shot on heavy wood arrows from either a 65lb or a 75lb Blackwidow longbow.
Cannot comment on the others as I have not had any experience with them, but based on my experience with the Grizzlys, I'd say you are spot on re the other broadheads.
Again, well done, nice video.
Best
