I was actually thinking steel would be less prone to fatigue induced stress fractures. What do you think about 1/8 steel? A little heavier definitely, but on such a small piece we're only talking a few ounces difference.
Realize the direction of forces, sideways, it is across the material. It would be very rigid in that direction. There would have to be a kink or bend started for it to fail.

Thicker won't hurt, but that .080 would be quite rigid. If it was flat, that might be a different issue.
