N4CC and I recently used male N connectors on both ends of the LMR-600 runs. 
The copper bulkhead we use for our external ground bus is loaded with 
Polyphaser and Transitrap devices that come with female connectors on both 
sides.  So, in our case, it was kind of a no-brainer to use male connectors 
on the shack end of the LMR-600 runs.

On the antenna end, we also used male N connectors with N female barrels 
that join short lengths of RG-213 to the antenna feeds.  This facilitates 
VNA measurements looking into either direction of the cable without having 
to hunt down a gender-change jumper cable or adapter in mid air.   The 
barrel is just broken apart for measurements into either the source or load 
end of the line.
