This is also the tracking weight I found to work best in my arm; it's all that's needed for good tracking and anything much heavier than that seemed to diminish its lively, open character.
. . . it ain't no giant killer.
I might have a different take on that than some. For me, a giant killer is a cheap cartridge that lets me enjoy my records. I wore out the stylus on my Goldring Elan because the cartridge satisfied me. Other giant killers for me include the AT70L, Grado Green, anything made by Stanton/Pickering (except the Epoch series), the M97xE, Linn Basik, and I have high hopes for the AT CN5625AL, which I've been using with complete satisfaction for a few months now (many years ago I had tried one and found it lacking, but its possible I had simply gotten a sample that had lain on a shelf too many years or had been improperly stored).
A few cartridges just seem to sap the life and energy out of the system (that is, the playing is less tuneful, less dynamic; it's harder to appreciate how the instrumentalists or orchestral sections are interacting with and complementing each other). Every Shure I had tried before the M97xE fell in this category, as did a couple of Goldring 1000 series cartridges, an ADC XLM Mk II, and an Empire I no longer remember the model of. Also, some cartridges are just tonally unpleasant to me, such as the AT440ML and a Rega Bias (though I find the Bias 2 in a friend's system a satisfying listen).
Some cartridges can go from mediocre to quite good just by supergluing the stylus to the body. Stantons, Pickerings, Shures, and the Elan are some that benefitted from this (though even this didn't help the Shures, except the M97xE, satisfy me). AT and Grado models seem to have a nice, tight stylus assembly fit that doesn't need gluing to let them sound their best.
And of course, every cartridge is limited by the turntable and tonearm it's used with. I'm a big fan of the Rega P3-24, but it's not an LP12/Ittok, and I've heard $50 cartridges in my Linn easily outperform cartridges costing hundreds of dollars when mounted in the Rega. A cheap cartridge you enjoy can be the ultimate giant killer because the savings can be applied to making your turntable better. For example, instead of upgrading the Basik cartridge the came free with my Basik Plus arm, I enjoyed cheap stylus replacements or other low-budget cartridges for a few years and banked the savings til I could buy an Ittok arm. The Ittok made low-cost cartridges perform so much better that I no longer needed a better cartridge. A high quality 'table and arm lets cartridges like the Elan or CN5625AL really shine.
