Personally, I don't think that there's any better camouflage pattern than a copperhead's. It seems to blend in almost everywhere, and still manages to look beautiful on a bow.

I was turkey hunting in 1992 in some wet swamp and had a cottonmouth hit me right below my right knee. He was hung up in my rip-stop camo pants and i pulled him off and twisted his head off.I felt something running down my leg and thought it was venom but when I pulled my pants leg up...it was blood.Didn't make it back to the truck before my bowels let go. When they gave me anti-venom, I think I bent the stainless steel table I was sitting on.Turned yellow around the bite and a few days later a lovely shade of lavender but it cleared up in a few weeks. I'm much more careful now 8-)
If your going to put skins on put the real thing on or just spray on Camo. There are lots of good looking skins that make great camo.Bob
