I use reflective arrow wraps. They aid in arrow retrieval....and if you're tracking at night......they can hep you in a BIG way. When I shot my buck....I stuck one in the ground at the point of impact. I stuck one in the ground at my tree (to be able to find the area when I returned to track). I stuck the broken arrow (found on the trail) up and it helped when we wanted to retrace the blood trail backwards.

Reflective wraps are great.
