[TowerTalk] Multi-Op Station Interconnect coax type?

I like the 1/4 inch Andrew superflex.  You can solder on pl259s with a ug76 adapter.  The
coax stays put when you bend it to fit. However as a solid shield it is not as flexible as
a braided cable.  (I also have a lot of short lengths of the superflex).
