I have used the Matrix sights since they came out and have found them to be very reliable. This year I bought one of the new Trouphy Ridge Mantis sights. I realy like it. The sight can be used as a pendulum or fixed sight. I have mine sighted up to 70 yards for the outdoor courses. I have a tree stand set up in my backyard and with the sight at the 20 yard mark I can move my Block target to right underneath my stand or out to 30 yards and the arrows hit spot on.
Good Luck,
