The OEM headshell is 7.6 grams.
SL-1200G/Hana ML Best Headshell
I have been looking at a Titanium and Carbon Fiber headshell. I think one is 19gm vs 12gm. The ML has published compliance and weight, but I can't find published figures for the Technics magnesium arm? Anyone have suggestions as to best way forward when looking for a headshell?
