not to mention the ease of finding the arrow after the shot for analysis. (sp).
That's why I use all white w/ 6" wraps. They're easy to find, easy to "read" (for analysis of the hit) and my wraps are reflective. On a pass thru I'll stick the arrow up in the ground, so that I can shine a light (for night recoveries)back (while trailing) towards the the POI, for reference.
To avoid confusion on the cock vane issue (having everything white)...I number mycock vanes, so that I know how to orient themon my string....inthe case of quick, follow-up shots, or...a possible second shot attempt.
