Ok, I think I've tried nearly all nntp clients available, and have not found one that works like I want it too.
Must support -
Multiple servers w/multiple connections
NZB Files
Combining partial files
PAN - No NZB Support ( I don't recall if it does multiple servers)
BNR2 - Does not combine partial files, so par2cmdline doesn't recognize the existing parts and just calls them missing
Klibido - Soooo close, but it does this retarded round robin assignment of part downloading, so if one server can't get its "assigned" parts, it doesn't have one of the other servers grab it instead.
At this point, I've resorted to running XP in a VM to run Newsleecher.
