I need a suggestion from you guys...

My app have few arcs(they would be static) and few balls(these would be moving).
Now i have following options:
1. Create both of them as images and use it in my app.
2. Draw them.

I also need to detect collisions between them.

What would you recommend? Using Quartz OR OpenGL?
My primary concern would be to move the balls smoothly on the screen.

Thanks.
