I have difficulty seeing my pins and target with my ross 337 and that was why i bought the z-point. only problem was z-point for a vertical bowis hard to set up. I imagine it should be easier to set up onan x-bow. One of the reasons i wanted an x-bow besides my rotator cuff tear is that its easier to sight in a single focus(plane) scope/red dot on an x-bow vs a vertical bow.
