The reason you see people using gloves to handle those types of snakes is because they tend to be high strung in nature, and arboreals have *huge* teeth and a bite from them is less than desired.
I'm in full agreement with Scotty. If you have an agressive snake on your hands, use a hook. There's been too many times a snake keeper has used work gloves to handle their snake, only to have the snake snag their teeth in the gloves. Gloves are only safe for the person...
