It's a great sight...I have one, unfortunately I can't use it because I use a 3 prong bodoodle rest and helical fletched arrows. With that combination, my cock feather (vane) is pointed up...I need to align the arrow so I get no arrow rest contact, and don't hit the fiber optics with the vanes.

Sure enough, I broke one of the optics....so now I use a Spot-Hogg Hogg It sight. I'll use the TR Matrix with a drop away or shoot thru (cock feather down) rest....maybe on my next bow.
