I don't think you are truly understanding Spider Rigging! You are not moving when over the fish. I basically see fish/structure and let wind/current drift me back over them. You want your lines at a 90 degree angle to the rod. This keeps them as close to straight down allowing for depth control. Maybe you are thinking of pushing or long lining?
