With the gray action wood, I would go with canebreaks, or diamondbacks. The black glass should make the pattern stand out. Black leather quiver with the same skin accents. Then get Guru to "snake" a dozen arrows for ya... :D No such thing as too much. LOL. Of course Cottonmouth skins are cool, and subtle.
Snake are awesome creatures, and one of the most attractive skins IMO. My uncle(who was really my Dad's best friend) used to have HUNDREDS. I remember walking into his house and the rattlers just going nuts....He was one of a few people in NYS lisenced for poisonous snakes. When he died, the majority of what he had went to various reptile institutions through out the NE.
