One of the benefits of using this layout is that it creates more asymmetry in symmetric balls.  Using a ball with a MB may not be the best idea, because you might end up drilling into the portion of the core that gives it the asymmetry already.

The cover only needs to be as strong as the lane pattern you intend to use it on dictates, just like any other ball.
