Right now I use muzzy 4 blade broadheads, which I am very happy with, and have been considering switching to magnus stinger 4 blades. The reason is that I think the thicker blades on the stingers might be better suited for moose and brown bears.
It is between these two heads, I don't want any other considerations, we already have 5 pages of other considerations.
The reason for switching is for big game. I don't care how your broadheads work on deer.
