Before expanding my own analyses to this area I shortly publish something of my own results from MyTrueAncestry. I know, here are many readers who don't give much credit to MTA and likely there are false and true results. However, I have seen that those results are usually in line with their customers' origins.
We see that my results focus on Estonian and Germanic aDna, but in my opinion the most interesting part of this is my older Trans-Volga Forest Steppe - Sintashta - Andronovo aDna. Were Trans-Volga and Sintashta cultures the same and one culture speaking IE language, or parallel cultures, the first speaking Uralic and the latter Indo-Iranian language?
