I am confused my choice.

Right now I have:

7D
70-200mm f/4 non-IS
50mm II f/1.8

I figure the 17-50mm would compliment my lens collection and pretty much complete it: I will at least have covered all of the range that I need.

I can't afford both right now.

My primary subject is motocross/sports. I particularly shoot hare scrambles (which is just a motocross race in the woods). The flash would be good for dark environments, but the wider angle would be good too because the trails are tight.

I'm not sure I fully understand the benefits of having top of the line dedicated flash like the 580ex. I realize it has more power, but is it miles ahead the cheaper 430ex?

I also have to take into account that if I shoot people, I will most likely need a softbox to soften the light, since it is still harsh light.

The main advantage I see to the light is being able to move it around and put it where I want, and use my 7D's wireless capabilities to trigger it.

Any thoughts?

I would say go with the 17-40mm f/4.0L instead of the 17-50. It also depends on which you would use more, the lens or the flash? Since your camera has a built in flash, I would go with the lens and save up for a flash later on.

Take Care,
