Having decided that the Infinity grips look and feel too good to keep out of my ES, I am suffering from a little brain overload from the 65,536! possible switching combinations:).   I'll have elevator and rudder trim on the coolie hat and the usual push-to-talk trigger.  For for the other switches, I go back and forth between safety-of-flight considerations (e.g., pump, start, various lights) and convenience-of-flight factors (flaps, autopilot and radio functions).  Recognizing that there is no "right" answer, it would be interesting to know what others think about this and what those flying have done and liked or regretted.  Thanks!
