weatherby, a couple of the guys I shoot with use the Spigarellis and they can't say enough good things about them. They are a solid rest. The one thing I have noticed is that all the guys that shoot them have customized them in one way or another. One guy made a custom mount for his bow and another made a custom launcher. The third guy that uses it kept his pretty much stock except for the attachment to the cable slide. Just food for thought.
