I like white crown dip and white nocks but looking at an arrow when shot you have a white point of less than 3/8" to keep up with. At lease white helical fletching gives you a bigger white object to look at. I like fur tracers too but they only show up when the arrow hits the target. In flight the tracers lay flat against the arrow, thus affecting the arrow flight very little.
Even though I like to watch an arrow in flight I never see my arrow until it hits the target. My bow and arrow are totally out of mind while shooting. I try to concentrate only on where the arrow WILL go. Ideally, everything else is muscle memory.
