Which balancer?

IIRC you cant balance a fluidamper as the silicon is a dynamic component. The housing and hub is rigid but the media in there is fluid. All are neutral without added weights. Thats what I heard from a balancer. ITs not that it will affect the overall balance, it will mask the real balance issue..something like that? Like slime in a tire, its 10oz of fluid silicon, but the tire doesnt go out of balance.....? My CAT fluid type balancer is probably the same balancer in chrome, heavy beast.
Ah, OK, so this advice to not install the damper applies to a fluid-damper type? I did not catch that...
