I'm looking to upgrade some of the parts of my Technics 1200G turntable.

The mat: is Airborne cork and rubber any good?

Record weight: any recomendations of a decent weight that would be a good match for a Technics TT please?

Interconnects: I'm looking at a 1m length Graham Slee CuSat50 to connect TT with phono stage (Graham Slee Reflex X) and 1.5m length of the same to connect phono stage with preamp.

I have a KabUSA tonearm fluid damper on the way as well.

I will address the headshell at some point as well but need to be careful with that because I'm conscious that it will need careful matching in order not to mess with tonearm mass, etc.

Currently using the original headshell and an AT VM95ML cartridge. Amp and preamp are Naim.
