Topic: Scarce rhel6 packages, many repos, how do I avoid conflict hell

In my crusade to get software for my many rhel6 boxes, I've stumbled upon Centos, EPEL, RPMForge, IUS, JPackage and Remi. This is the status of each:

Centos: no centos 6 yet
EPEL: rhel6 support works
RPMForge: rhel6 support
IUS: no rhel 6 support
JPackage: no rhel 6 support
Remi: rhel6 supported

So I can theoretically get packages from Epel, Rpmforge and Remi. Would these repositories get along fine or will I have to pawn my children to escape conflict hell? Once Centos, JPackage and IUS support version 6, would these repos get along too? Is there a set of repos that every redhat admin compulsively installs because they work together fine?

RHEL-6 + EPEL-6 + remi-6 work fine (designed to)

I can't say for others (but I know RpmForge often have issues with EPEL).
