RE: What are those fluffy things called?
I had some, called them tracers too, didn't like them.
You want to track your arrow in flight ? 3 big white feathers will do it. Want MORE visibility ? Buy 3M white reflective tape, use Fletchtite Titanium and the bond is very good, and a flashlight will make that shaft GLOW at 100 yards at night.
