I was one of the guys who listened to others negative comments and also feared what those bristles would do to flight paths...........then I tried one.
Great rest...........period. Easy, silent, accurate, holds the arrow. What else is there?
An interesting article in Peterson's last month showed slow motion camera footage of a WB in action. 2 things that were seen in the still photos were that the bristles are actually pushed out of the way (forward) as opposed to being sliced through. Secondly, the arrow vanes are at least half way through the bisquit and the arrow is still on the string!!
That little bit of info could actually be the answer to everybody's questions about why the bristles don't effect flight. By the time the arrow leaves the string the vanes may not be in as much contact with the bristles as some people think.
I couldn't care less either way..............the only proof I need comes from my shooting sessions and it passes with flying colors. It was an interesting read though.
Try one........then you will know for sure. There are plenty of other rests out there if you don't like the WB.
Save yourself some time and money and try the WB first though
