[ldm-users] NDFD via CONDUIT

good morning ...
got a quick question I'm having a tough time finding a reliable answer...

I have always used the 'assembled' NDFD GRIB files from
ftp://tgftp.nws.noaa.gov/SL.us008001/ST.opnl/DF.gr2/DC.ndfd/AR.conus/

the individual files are on CONDUIT from another ftp server,
is this a matter of convenience ?
or reliability?

didn't know if I wanted to add more to my LDM stream..
or continue to 'wget' from the NWS servers ...
