Which is the "best" version?
It has been claimed before that the "AU" versions supposedly are the strongest, but I disagree with that statement. In my opinion, you should try each variation for the rune yourself, vibrating it for a few minutes intently and then feeling the energy and taking notes on how it feels to you. Then after you seperately tried all of them, it will be easy to figure out which version resonates most with you and your goal.
Of course avoid the VoC when testing a rune version for the first time.
This may seem a little time-consuming to some, but if you cant even have the patience to spend a few minutes a day for a few days to figure this out before you start an important working, then chances are your working would have failed anyways out of laziness.
Also, the short versions of the runes like "Oss" for Ansuz and "Sol" for Sowilo, are best used for meditative and spiritual purposes.
