Re: [ARSCLIST] lateral cut switch

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.
