I have opened both repeaters.  The VHF already had the blue hardline in it, the 
UHF however I replaced with superflex.

I may try something different.  Hardline up the tower and for a patch cord 
(about 10 feet) up the mast I'll use superflex.  I'll have to play around and 
see what I have still.

The preamp has made a big impression on the RX without the amp.  I have not 
tried the system without it and the amp at the same time.  Might be worth a 
shot.

I don't have any test equipment that would work for the digital dstar so it's 
more of a trial and error thing.
