Everyone agrees, standard trim speed is about right for take off/landing but too fast for cruise. There are devices like Safety Trim that will slow it down based on airspeed. I use my Trio autopilot knob, which can control the electric trim even when the servos are not engaged. You can program the trim speed vs airspeed. It?s *almost* the same feel as manual trim, with the amount of trim proportional to how many clicks you move the knob, independent of time.
