Dual thumb drill on symmetrical

How would the dual thumb layout work on a symmetrical ball.

That isn't going to be an issue.. I have a ball with a 4-5" pin that will put the cg in a position to put the weight hole where it needs to be.. I'm just wondering about what it will do reaction wise for a symetrical vs an assymetrical..

I have the drilling on a street rod solid and it gave me the reaction I was looking for. There have been several people on here whi have put the drilling on a symetrical ball and had great success.
