I tried that rest back when I first started bowhunting. (I didn't like the way a whisker biscuit crinkled my vanes). It worked OK til the day we had to track a wounded hog. If you have an arrow in the rest, and jiggle the rest, the arrow can fall down in between the prongs. Well, guess what? It did just that on me with a wounded hog running around charging us. I was frantically trying to get the arrow out from between the prongs. Exciting moment. Went back to whisker biscuit after that, and found some vanes that worked with it.
