Pendulums work really well out to a certain yardage depending on your draw weight, arrow size, ect. I've looked at the TruGlo tritium fiber optic pendulum and they are really nice. I've been shooting a TruGlo fixed pin with tritium fiber optic, and in my opinion you won't find a pin anywhere that gives you that extra little bit of edge when it comes to hunting in low light conditions. They just stay brighter longer than anything else I've used, and I've quite a few of them.
