Jagdzaku,
To answer your question, almost. With mass behind the position of the cartridge, 100% of the weight difference does not subtract or add to eff mass. This is a trivial amount. The stock shell looks to be of very high quality, but it might be interesting to experiment.
To clear up some misconceptions, if you increase the weight of the counterweight and bring it closer to the pivot, eff mass will decrease with the change of distance.
I think too much emphasis is placed on resultant resonant frequency. IMO you'd be better off asking users which carts are a good match, which combination seems like it's made in heaven. Some carts seem to sound better with mass that puts them a little out of the recommended resonance range. While you don't want that undamped resonance approaching the audio band or excited by a warp, best results are not defined by "perfect" 10Hz resonance.
Regards,
