Cartridge for stock Technics 1200G tonearm

It can be any mid compliance cartridge, just do not buy low compliance and high compliance cartridges. Recommendations are already on audiogon in many posts regarding this turntable and tonearm, use seach option. This is what has been posted recently: https://forum.audiogon.com/discussions/technics-1200gr-owners 

what is the issue with a low compliance cartridge- as long as the resonant frequency is ~ 10Hz?  
I'm using an Ortofon Cadenza blue on the GR, compliance is 12 um / mn and the calculated resonant frequency is 9.6Hz.  so far it tracks and sounds great. 

No problem, but 12cu is not the lowest compliance and normally low compliance cartridges are also too heavy for stock headshell to balance it. For example my low compliance Argent MC500HS is 8cu (7gr weigh) and it was impossible to use with most of the headshells.  

Anyway here is the article about it http://www.ortofon.com/support/support-hifi/resonance-frequency

It’s important to know cartridge compliance measured at 10Hz (not at 100Hz). If the compliance measured at100Hz (it must be stated in the cartridge manual) then multiply it on 1.7 to transfer it to 10Hz compliance. Then anyone is free to calculate resonance frequency. I do that with my Cardas LP.

High compliance cartridges (30-40cu) are lightweigh ones, you may need silicone fluid damper to use it not Technics tonearm which is not optimal for high compliance cartridges.

So it’s "safe" to use Mid Compliance carts with stock shell on this tonearm, that’s pretty easy.
