Word on the street is, that currently there is no aftermarket pistons/rods provider that is actually 100% on-spec Bob weight of the OEM material.

I think that it depends on spec. Some builders have much lower tolerances than others. I agree with you 100% a truly balanced engine is better. But It is my understanding that they are within 1% of each other, and factory. Now is that accurate enough for you? I'm not sure. I do not know how accurate they are truthfully , but I can say for a 100% fact that when I replaced my pistons and rods the carbon build up on some pistons vs others could create a difference greater than 1%. If I pull the main bolt to do studs I may pull the rods and pistons and check the weight. I should have done that before.
