Bubble and Fly rig

[trophytrout89]

I wasn't sure if I should post this in the fly fishing forums, But has anyone tried the fly and bubble rig. I've done it a few times in the past on a river but never had any luck with it. I know a lot of people that love using it on lakes and ponds. But my question is when your fishing it on still water, such as a lake or a pond, is there a specific technique to moving the fly. Or should it just sit there?
