Stand down range from a shooter and hear the noise your feathers make going downrange. You'll never worry about broadhead whistling again when you realize your arrows make lots of noise regardless.

when i first got the ww they made a lot of noise because my aarow weren't tuned very well. now that they are tuned i can't say that i notice any noise.

I've had only one Woodsman glue-on 125 gr, out of 18 make noise.  Being on straight is the key thing.

But bigbadjon is right: feathers make noise also.  I just don't want any more than I have to have.

But vented may produce more than non-vented.

The 125 woodsman is a great head, but it is loud!!! in my setup. I went to a 175 VPA and have not looked back. I think anything non-vented will be quieter than a vented head.

Good Luck!
