I would not recommend using the churro tube for sure, it's not designed for such stresses.

I feel like anything that would bend a steel hex shaft, even 1/2 inch means you are over compressing the ball and I'd be concerned about popping it. We bent what I think was brass today when we over compressed on one of our prototypes.

Also gonna throw out there that the banebots wheels are insanely good at gripping this ball. In my, walk around the shop and touch stuff to the ball, they were by far the best. Didn't have any VEXpro wheels around though, I've heard good things about them as well.
