I'm also in the process of adding a 3 gram headshell weight to a JMW 9 arm.
I found that by placing the weight between the cartridge and the headshell had caused the rear of the arm to be far too high (after VTF adjustments) to the point where the stylus lift bar, adjusted to its highest setting, will not even be high enough to lift the arm off the record.
I'll have to go back and place the weight back onto the headshell.
