"Just by looking at it, it looks like 5+ inches based on where the CG is normally located on this ball. Plus, that's not seeing it in person. Plus as you said, CG way out of line so I am assuming the CG wasn't in the 900 Global's label. "
Quite the contrary. I confirmed the cg befor i drilled it and it was dead on. As this is a symetric ball there is no marked mass bias for ity to be out of line with. The ones they were selling that were out of line were all in the break family. Also as far as looks go keep in mind my span is 4 1/2
