Wow, I have to be a minority here... I'm shooting a new Vital Bow Gear Camelback pendulum sight.

It's a great sight for the money and has a lock-down feature in the top/back of the sight. I've sighted it in for 20 yards on flat level ground and am good to go. I also shot it from up on my back porch roof, shooting downwards at 5 yards, and it was dead on into the Block 4x4 target. With my bow shooting roughly 267 fps, I am probably good to about 30 yards at best with it. But the best thing is there is no guess work involved. 17 yards, 22 yards, 9 1/2 yards, etc... it doesn't matter. You're dead on no matter what. [8D]
