So sneaky bow your saying Iron Will Broadheads will kill faster because they have better edge retention,, so another random head that's as sharp as it can possibly be (for sake of argument) vs the IW put through the same spot on a deer or whatever the one that got stuck with the IW goes down first?
I haven't seen the IW heads but I'd go with Sneakybow if the IW is as wide as a Tree shark or maybe a tad wider because the treeshark I'm told can cut the entire heart in half on a med to small deer on a hard quartering shot "so I'm told" ,,,,, I think though if we can group multi blades into this I'd vote for the big 160gr snuffer to snuff the fastest and that's only if I have to pick a head,,,,,,,, I know two blades bed them down quicker sometimes within a few feet after pass thru than anything I ever seen and that's based on my experience with Ace Standards, Grizzly, Stos and Stingers,, I can only imagine what Big Jims 1 1/2" 3 blades can do
