Actually a good headshell should not "wiggle" in a Technics arm. I am back in FL now and here are actual weights for headshells in my collection using a digital kitchen scale.
Technics. style w/azimuth screw - 8 grams
Technics. style w/o azimuth screw - 9 grams
VAS supplied generic (similar to Ortofon) - 10 grams
Ortofon. - 9 grams
LP Gear Zupreme. - 12 grams
Yammamoto HS-4S. - 12 grams
Silver generic (similar to Technics w/o azimuth screw) - 9 grams
Cartridges set up now include AT-VMN760xSL, AT-33PTG/II, plus I re-set up 2M-LVB, 2M Mono SE, AT-150ANV, VAS,Nova Stereo, Vas Vova Mono, AT-33 Mono ANV. I might have missed one or two. Anyway, I am trying to develop proficiency using AnalogMagik so all of these have been done over the past week. Mono cartridges don’t require vertical compliance of course so only lateral resonance is significant for them. Resonance should be between 8-12 Hz both vertical and lateral for stereo cartridges. I reconfirmed again that head shells that weighed 12 grams drove up the resonance to frequencies to be outside of this range for all of the cartridges on this list. Like I said in the beginning, unless you really have special knowledge you would be well advised to stick with the OEM Technics head shell. It is the only one that I have found that weighs only 8 grams and has azimuth adjustment. Be aware, however, that not all Technics OEM head shells have azimuth adjustment. Buyer beware. In case it is not clear, azimuth adjustment is not needed for mono.
