A slow twist in the ladder line will tend to equalize the effects of
external influence, but the effect such influence has on the ladder line
will depend on a few factors; do the two wires of the ladder line get
equal treatment from the metal or whatever, how much of the ladder line's
length is near metal, where in the scheme of things from one end of the
ladder line to the other (parts of a wavelength)is the metal?  Etc.  And
most important, is the ladder line part of a resonant system or is it 
a flat 400 Ohm line.  If it's a resonant system it will tolerate a lot
of weird routing if the system can still be tuned properly.  Ogden Nash
put it nicely, "With mules there are no rules." Same thing with ladder line.
