it would be worth checking the BRCA website and the EB rules

Chris is right regarding the EB rules....
I've not personally seen the rotor from a Novak BL, but I suspect that if the "L" series still run the 14mm rotor then it must have a slightly larger shaft within the magnet area, thus reducing the quatity of magnetised material.
Anyway.... as Jim76 says the smaller rotor the smoother the power delivery and the more RPM's. I have a feeling the smaller rotors also get a tiny bit warmer too.
