I think the Ashby testing is a nice novelty to discuss...I am also sure it has little relevance for most of us

Most, but not all.

Absolutely. And, as I said, if you're hunting big buffalo with tradbows, stick to good two-blade broadheads.

The main knock on 3-blade broadheads in Ashby's testing was not their lack of durability, but rather their relative ineffectiveness in penetrating bone. While being a tough head, the VPA remains a 3-blade which according to the study does not penetrate bone as well as a 2-blade, all else being equal.

I love the VPA 250 three blade on deer and everything this size of animal and down . But when I hunt moose I go to a 2 blade. Vpa or werewolf either of them are great to shoot

FWIW, I never shot at a buffalo yet neither at a dead cow       :D      
As I did myself you can make your own testing. All bows in the low to mid 60# at 31" all those game killed with 1 1/2" 3 blades VPA/Big Jim
First the theorical part comparing on heavy density foam different design and width and see not that much difference between large Magnus 1 160gr 1 1/2" vs VPA penetrator vs VPA/big Jim 1 1/2"vs VPA 1 1/4"

     

     

Then practical part on big game. I am sorry but we don't have elk neither moose here and the biggest critters I killed using VPA / big Jim are only  cape eland. A old cow, a young bull and 2 mature bulls. All 1200#+ Up to 1700# and rib thickness from 3/8" to 1/2". I got complete pass through on the young bull and the last one.

     

     

     

     

I don't know if it s significant as these critters are smaller although in the 500+# range,  but I did test those VPA multiblade on a couple of mid sized animal and It worked fine as well so you don't have to worry for deer or elk hunting or anything in North America with your set up with VPA multiblade 1 1/8" IMO (despite Ashby studies).
