The RA material is indeed some pretty good stuff, but I find myself not needing it lately. The knowledge it presents seems mostly self-evident nowadays. And there is a SLIGHT tone of distortion in it as well. Much less than in practically any other channeled material, but still...

The MAIN distortion is that RA strongly encourages your polarization towards Love and Light. Which sounds nice enough, but isn't quite the ultimate truth. All this STO vs STS yammering will creep under your skin eventually. Because it is distortion! The RA material actually clearly states so itself, but still manages to push STO vs STS ideas over and over.

The key is achieving mastery of all aspects of Energy, AKA perfect Balance of the Force, not being a "Lightsider". The RA material would have been infinitely more helpful if it had managed to get this point across better. But I guess the problem is the people who did the channeling weren't always asking the right questions.

When it comes down to it, all knowledge is available within. We really don't need to study RA channelings or anything else, as long as we get in touch with our own inner guidance.
