I checked out the TR Matrix but ended up with a Virtual Bow Gear Trapper sight. It only has three pins and they are vertically mounted also. However the fiber optic string is of a larger diameter and that makes the sight brighter and easier to see. It was about fifty bones less than the matrix but that alone wasn' t the buying factor. If Trophy Ridge had bigger fiber optic string, I probably would have boughten one. Hope this helps.[]
