Seasonal Special - Fly & Bubble Casting Rig, Flies, Leaders & Magic Casting Bubbles

After trying the bubble casting rig, I found that when you cast, as soon as the bubble lands, the lead gets pulled straight down with it, pretty much on top of it. So I am not sure if the leader should be longer, but the way it is now everything just comes crashing down and probably just scare the fish away.I will try it again next time I go out in the river, this time it was lake fishing I was doing, but I can't see therebeing much of a difference.
