ZYX Ultimate Dynamic cartridge


I have a ZYX Premium Omega G and thinking about uppgrading to ZYX Ultimate Dynamic Cartridge.
Seems only choice is copper wire, cantilever made of carbon (instead of boron).
Any experience?

Many Thanks,
Clabe

ZYX copper was much better than ZYX silver coil when I tried both. 
Airy 3 and Premium 4D are two models I used it the past. Also ZYX CPP-1 headamp with its special zyx resistor made with the same copper coil wire used in the cartridge coil.
