It sounds like the cables that take the paths alongside the nose gear tunnel
and ultimately connect to the more-directly-run cables are the problem.  I'd
be looking for a less tortuous path for those two, smooth out some of the
curves if possible, and lubricate them with teflon powder, as mentioned by
Charles Patton earlier.    My 2c FWIW.

Yes Greg, Marv is right. It would be nice to hear how many followed the early directions - BFB (before fast build 320/360s) - and actually routed the crossing center cables to the floor and then up thru another "S" to their eventual exit at the nose gear tunnel.  If the procedure was handled carefully, the result was enough friction in the system so as to provide a "set it and forget it" rudder trim system.  If not, excessive binding. 

 

I ran mine horizontally on the interior of the top of the tunnel, crossed at the seat back and exited the console just aft of the nose gear well.  No friction and a very twitchy rudder that was finally calmed with a servo-controlled spring-managed trim system (full right for takeoff and climb, full left for cruise).

 

If you are able to route new nyla-flow more directly, it may be possible to use the original cables with the length gained thru straightening.....
