If you take the high percentage shots, almost any broadhead made today will do the job. Take a poor shot like quartering to you, hard angles, and so forthI dont care what broadhead you use it will end badly most of the time.
More research on lower profile fixed blades is being done to help with arrow fight. This is encouraging to fixed blade shooters. The mechanicals are also getting better due to the research being done today. The Rage is one example as well as the Rocky Mountain Snyper. TheSnyper has been around for a while, the rage just has more marketing behind it, basically the same head. (Rear deployment.)

I have almost always shot a fixed blade. Thunderheads andMuzzy. This year I am trying theSnypers.2 blade.
