I was responding specifically to someone with a VPI arm which had a very high RF with a given cartridge. One of the possible "fixes" ws a 3 gram or whatever weight from VPI which in THAT particular combination would have lowered the RF 1Hz or less. given the problem not really worth the effort.I never said that increasing the mass at the extremes of the arm would not increase the inertia, in fact it does.
As for the fishing weights the amount a given amount weight effects the effective mass is proportional to the location relative to the pivot. In other words the 1 gram at the headshell has a much greater effect than 1 gram at the exact pivot point. It may increase the rotational mass without increasing the effective mass.
Now that can be a very interesting change in the arm mass but not the effective mass.
Cheers!
