I'm on the same situation and I use IntelligentMirror and squid to
cache all the rpm packages regardless of the mirror.
Also I set up the mirror line on the /etc/yum.conf
One word of warning if you want to go to the same route: you have to
setup 2 different mirrors for x86_64 and i386 arch., because there are
i386 packages built for the x86_64 platform that have the same name
but different checksum/content than the one for i386.
