This is very nice, but the stylus on original Ruby (RS9R) is elliptical.
There are better profiles from Grace for F9, also profiles from FR14 (F14) are compatible with F9. Grace own Advanced Luminal Trace profile (RS14AL clear color) or those blue color profiles with "F" on them with LineContact type of the diamond.
Don’t know enough to suggest a cartridge, but options abound. I use a vintage Grace F9 Ruby with great pleasure.
