The only animals that i have hunted that notice my flourecent yellow feathers and dip is turkeys and coyotes. It seems in the last couple years i have been using these arrows those 2 critters spot me more in a tree and i think its beacuse of my arrows.
for rain days go to walmart or whereever and get those little rubber bands that girls use in thier hair when they make braids (they are small like an o-ring) and wrap a peice of seran wrap around your fletching and put the little rubber band to hold it. keeps your arrows dry in the quiver. when you are ready to shoot just pull the seran wrap off and dont worry about the little rubber band it wont affect anything.
