The mass isn't an issue if you use a low mass headshell with a medium
compliance cartridge in a medium or low mass arm. It could cause problems,
but depends on what arm and cartridge you're using. I've had problems with
those low mass headshells where I need to use greater than 1.5 grams of
tracking. With one mono cartridge that was supposed to track at 3 grams, I
added a hex head bolt to the headshell. I suppose a quarter and some tape
would've worked too. And as far as balance of the tonearm, I don't see how
it could really mess things up unless it's a unipivot. The forces applied
to the end of the arm are at funny angles anyway. You've got skating, warp,
off-center, and any anti-skate you may apply. That's why most arms use
gimble bearings (or knife edge, or...) instead of a unipivot.
