The Rev, a rest like that with metal stuff sticking down, fletching contact would be very detrimental and likely to occur on occasion. With a WB fletching contact is your friend. It's a good thing. It guides the arrow, supports it, and keeps if from making noise when walking through brush. On most rests, fletchng contact is your enemy. With the WB it matters little or none where your fletch are oriented. The fletch contact is supposed to take place and is what you want when using a WB.

For what it's worth. I have used WB and found it okay, but if I were going to use a contained rest, I would go with the Hostage. Less contact with your arrows and none on your fletching, comparred to the WB.
