What is the "best" cartridge a Technics 1210...

I had problems with antiscating less than this on Hi Fi News testing record. The tracking tests were not good.

you can send me a link to check that Jelco headshells, although I prefer something from Japan :)

@lordvampire Grace HS-3 is lightweight shell if you want classic japanese vintage headshell, better one is Grace HS-5 carbon headshell with treated holes for the screws in the finger lift of the shell - that’s nice option to screw the cart from the bottom, not from the top of the shell (no nuts needed in this case). You can also look for the Orsonic AV1 shell (it looks like a catamaran boat :)

For the ultimate, but very expensive, look for the new ZYX LIVE-18B from Nakatsuka-San, i use this one with my Glanz MF61 cartridge. 

ZYX LIVE-18B looks impressive. How much it weights?

Btw my upgrade plan - I changed the mat, the cartridge, I have the discovery wiring, need to set it. I ordered oyaide silver headshell wiring.
The only thing left is the headshell and the isonoe feet. :)

And I think I'm ready :)
