Here's an example of what I was talking about with the custom fabrication, our 2005 bot. My dad and I made a mold specifically for the second stage of the arm (c-shape). We laid two different configurations: a 3lb heavy duty, and a 1.5lb light duty. We had the weight, so we ended up using the heavier one. the arm though is indestructable. It's great to see the reactions people have to me hitting the light arm against a brick wall without it even scratching.
