I would love to see a grizzly style 2 blade (the gold standard in penetration) vs Centaur single bevel big game head vs a Snuffer (Gold standard in large wound channel 3 blade).
This could be excellent when considering the wider cut on conctact 2 blade heads, especially for larger game like elk/moose. It would be a good visual comparison of where they fit in.
Aside from all that, I would also love to see the large 3 blade grizzlys! Because they are about snuffer size, but have a taper ratio comparable to the legendary woodsmans!
