I have read reviews elsewhere and seen people here claim the Shun Mook Mpingo (wood) discs work.....seems incredible if true since they are not very heavy and apparantly somehow "tune" vibrations. (of course they are not cheap!)
I do use some cheap Mapleshade Heavy Hats which are brass discs in two sizes you place on top of gear to control vibration, the benefits if any seem to be small.
In general I don't see much mass loading of gear used now, since there are many advanced vibration management
systems.......Aurios, Sistrum etc. which seem to be very effective.
To answer your specific question I would use neither of the two objects you are inquiring about.
