Don,

On the Nelson or Jett powered Quickees or Quarter 40s the only time you should need to touch the rudder is on takeoff and landing. If you need to use rudder to hold a perfect knife edge, you plane is improperly set up. The C.G. should be adjusted, rather than the use of rudder movement or rudder trim.

As to Mode 1 vs Mode 2 I have no opinion. I learned Mode 2, and that is all I have ever flown.
