... however, I placed a gentle curve in the top pull-pull for the elevator, where it will
be exiting through the stab, to match the contour of the guide tube.
I then bent it back, ever so slightly, to point at the control horn.
The result, if I pull the wire out, is a *very* relaxed looking "s" shape, near the tail.
This served to make for extremely smooth operation of the system.

Mine works perfectly. I suppose the argument could be made that my bend could be
straightening out under a heavy load, but I can't see/feel it happening.
The wire "pushing" from below is also helping matters immensely.
(So much that the thing MIGHT fly with the upper rod disconnected, though I hope to never test that.)
I'm sure that the supplied rods offer far more resistance than regular cables would,
but I'm flying a normal 4.8v, 600mah pack, and am still getting my normal amount of flights.

I haven't experienced any binding, or servo-stalling issues at all.

I'm sure the pull-pull purists will say to throw the rods away and use cables instead
