just a question, i had an rs-1, which did not have a marked mass bias. reading a couple reviews, it seems like the rs-x does? is this correct? just surprising b/c i thought the core determined mb strength, and the two balls use the same core i thought. lmk

NO....the RSX does NOT have a marked mass bias....she's as symetrical as it gets!

MFortney...NO mass bias. They proboble ment CG, or they went and measured 6 and 3/4 inches from the pin through the CG to find the mass bias marking.

Roto in their drilling instructions tell you how to locate hte mass bias on this ball. Draw a line from the pin trough the cg. the mass bias will be located on this line 6 3/4 inches from the pin
