I'm about to record a symphony orchestra and could use some advise...

This is a professional orchestra (Sundsvalls Kammarorkester
http://www.sundsvallskammarorkester.nu/). This is a full orchestra with
all the sections/instruments, but not so many of them. They are perhaps
30 musicians. No solo parts here. Purpose is for their own
documentation.

The room is approx (from memory) 15-20m x 30-40m x 8-10m, wood in walls
and floor. There is a balcony along three walls. I'm not allowed to have
any microphone stands on the stage/floor, so I'll hang them between the
balconies. In front of/over the orchestra.

I've got 2 Pearl DC-96 (cardioids with rectangular large membrane). I
also have access to three Neumann KM83 (the older omnis). I've got an
RME Quadmic (4 ch). In order to use five mics I need one more
preampchannel but that can be organised if needed.

I've been thinking along various permutations of how to set up.
- the three omnis in front (violins, conductor, celli) + one or two
DC-96 over the woodwinds
- DC-96 coincident pair at conductor + KM83 pair over woodwinds
- DC-96 coincident pair at conductor + KM83 pair wide spaced in front of
orchestra (violins/celli) + KM83 over woodwinds
- ...

So, my two questions would be:
1) How would you these microphones?

2) How does one hang mics without loosing control of place and direction
in 3D space when all I've got is a (long) piece of string and not much
more.... The balconies go along both long sides all the way by the
orchestra, but not on the short wall behind. So far, all I've come up
with is how to hang a pair. I'll set up a string between the balconies.
Thread it through one stereo bar. Put a gooseneck under the bar and a
new bar on the gooseneck giving a "H" sideways where I can control the
two mics. The bar will align with the string and gravity will keep the
gooseneck pointing down so I can point the two mics hanging under the
lower bar where I want. There must be a simpler way. How do I hang the
mics that aren't in a pair?

sincerely
