What matters, is how much you change the internal pressure on the ball.
So, A single wheel can compress the ball to a smaller diameter than a long roller because it has less contact area.

All that being said:
Our prototypes ranged from 2 to 8 inches. But you are best off making a prototype, or designing something that can adjust the compression easily.

OR, look into using gas shocks. The rule of thumb is to compress with 3-4 times the weight of the ball. A quick search for should clear up any confusion. (I particularly like 1902's 2008 bot)

Thanks for this! I was just really looking to see how much variation people are getting. We have made a prototype single wheel intake but haven't really been able to gather much info from it due to the poor construction of it. I hope to be making a second prototype that is more robust.
