They are proned to breakage and also cut into the retainers. Are the flat dampers really that helpful?------------------

Premium quality springs do not break
They will fatigue, but they don't break.------------------

I would say yes. I'm no expert but my understanding is that the dampers are there to help with harmonic vibration. In other words it changes the natural resonant hz of the spring assembly to something above your operating RPM. This is to keep the valves from bouncing off the seats at higher RPM (relative to the springs max rpm). If you want to get away from dampners you can go to beehive springs. I guess the have no natural hz therefore do not need dampners. HTH,
