I purchased a WB when I bought my Switchback last year and shot it for a couple of days. I liked it for the containment feature, but that was it. I didn't care for the vane contact or the sound of the fletching tearing through the biscuit. Don't get me wrong, it is an outstanding rest. But the drop-away(QAD ultra-rest)I purchased gives me arrow containment; its quieter; there's no speed loss; and there is no fletching contact. For anyone that is considering one vs. the other, go to your local bow shop and try them. IMO a drop-away is better.
Dead deereither way.
