ANIMALS WON'T REACT TO ANY BROADHEAD ANY DIFFERENTLY THAN ANY OTHER.  

What matters is what a deer hears from where it is listening, not what you hear behind the bow. Whatever you hear behind the bow, if you SAFELY listen down at the target you will instead  hear the same noise from all your heads. There will never be a deer listening in your footsteps behind the bow. Deer in front of the bow will hear all heads and react the same, so it doesn't matter what head you shoot as far as noise.

This has been independently proven. It's only a guess by listening, and also audio graphed to show those results.

Bottom line, broadhead noise isn't a matter you can control by listening behind the bow and picking one. One less thing to worry about.
