The 640 has the self centering notch on the nose gear which works pretty well in keeping the front wheel centered in flight. You can adjust the rigging of the rudder to give some offset, i.e.- the rudder will offset slightly to the right when the front wheel is straight. Since the front wheel is held in a centered position in flight, this slight offset in the rudder essentially provides a fair amount of fixed trim to the rudder. The key is fine tuning the rigging during test flight to give feet on the floor coordinated flight in your normal cruise configuration. That way you won't spend 3 hours mashing the right pedal while cruising. If you don't do a lot of cross country flying, you may want to consider some type of variable trim system because you can only rig the rudder perfectly for one specific flight configuration. Unless your airplane is bent or otherwise out of rig, there should be no need for a fixed rudder trim as long as you don't modify the self centering design of the nose gear.
