I've read articles claiming that keeping your jig horizontal is very important........I don't think it is. In fact, I know one very accomplished jig fisher that always hangs his jig vertical and claims it increases his hookup ratio. I usually fish mine horizontal, because I think the tail has better action when you do, but I'm not sure it makes all that much difference.
