Which way the navel ends up in your shooter depends on how the balls are loaded, and how you pick them up.

Since the navel is probabally a dense spot of plastic in the foam ball, its should be heavier. therefore a ball on the floor would tend to roll till the navel is down, like an out of balance wheel will center itself with the heavy side down.

So depending on how you load your shooter for auton mode, and how the balls move through your machine, the navel my end up in random positions, or it may tend to gravitate towards one orientation in your shooter mechanism.
