Angier et al:
The dual control replies are all valid.  I decided to
install them in my 320 and saw problems right off.  Mostly
they are small and correctable. I discovered immediately
that hot gluing the tubing is not a good idea. Hot glue
distorts the vinyl and it stays that way.  I first heated
the tubing slightly with a heat gun and got it as straight
as I could.  I then laid out the cables and cut them and ran
each in its tube.  Then I streched out the runs clamped them
on each end, snug but not too tight. I taped, laid weights
on, or otherwise got each section of run in place and
microed.  I did not like the outside pedal attachment.  When
you move the pedal fwd and back it drags the cable in and
out from the side.
Fix:  I made a small ell bracket and attached it to the
pedal bolt then to the cable adjust linkage.  This allows
the padal to move full travel, (if you need it), and the
cable to stay in line with the fuselage tube.
After several samples of springs from the local farm supply,
I found a set with the right tension and length to keep the
pedals upright and not too tight.  With pedals on both
sides, no right side brakes, they work smooth as glass.  Do
not lube cables or tubes with any wet lubricant.  It will
only collect dirt.  Use a dry silicon or graphite if you
think you need it.  The layout in the manual works fine. 
I've seen a couple of L320s with no springs and the rudder
flops around like a rag in the wind.  Not my idea of good
building techniques.  I didn't go for the extra brakes
because of the lock up problems reported.  I don't think
they are a good idea on the "passenger" side anyway.  What's
the first thing a passenger does in a car when "they" think
there's a problem?  They try to push their feet through the
floorboards.  I have pictures. If anyone is interested, I
can email them.  Also, I've built the RST switching panel
with marker beacon and intercom, and all my antennas. I
highly recommend them.  Also, get Jim Wier's antenna book. 
The stuff is all simple and it works.  I've talked five
miles from my shop to the airport on a hand held connected
to the com. antenna.  Crystal clear.
