Hi Siamsa,
If you're seeing something like mikado sticks, then things are working fine. It's just a matter of using it to get the result you want. Basically, the Speed Line presets work in reverse (sort of). For example, if you want black speed lines, over a white background, you'll need to fill the background in with a black color, and use white when laying down the speed lines. I know, it probably sounds confusing, but once you see it working, it'll make sense. So here are the steps I normally use (for better clarity, view the following images at full screen):
