Why do you think it would be difficult to mass produce a neutral balanced item with todays technology?
The only times in my life where I actually saw a broken snout on the crank was blower motors with big toothed belts and one moron with an 8 inch externally ballanced damper which flew off with the end of the crank going down the drag strip. Never a FD or some other high performance damper.
My first 427 got an ATI

If I understand the design of the FD, the fluid inside (silicone?) is dynamic and will settle in whatever position is required to dampen the harmonics based on the harmonics generated by the rotating assembly. Have you ever seen the little steel ***** that are thrown inside your tires which move about freely and balance your tire? Similar principle I would think. Also, it's not a balancer but rather a damper according to FD. There is a difference.

love my Fluid Damper., I got to see and hold and examine a Fluid Damper at SEMA. There is only 1 large ring in them with a very tight surrounding of silicone. ...here is a cut and past from fluid damper with a nice picture :

What is crankshaft torsional vibration?
Every time a cylinder fires, the connecting rod hammers the crankshaft, making it twist as well as spin. After every twist, there's a rebound as the crank unwinds. This twist/rebound cycle is known as torsional vibration and if not controlled, it will result in rapid bearing and crank journal wear and can lead to a broken crankshaft.
What's the problem with a stock damper?
Stock dampers are tuned for maximum effectiveness with a stock rotating assembly when it's spinning at low rpm's. When the pistons, connecting rods, or crankshaft are changed or modified, or normal rpm range is increased, the effectiveness of a stock damper is reduced.
What are the key benefits of using a Fluidampr?
A good aftermarket damper protects your crank. Fluidampr is in a class all by itself, because it is designed to provide maximum control of all engine harmonic vibrations, regardless of the rpm at which they occur and regardless of the crankshaft's natural frequency. This translates to maximum protection of the crank, main bearings, related engine components and more consistent power output. Also, Fluidampr is maintenance and repair free. Fluidampr is effective on both race and street applications.
