The Elder Futhark 24 style (also referred to as the Swedish runes) helps you to write Swedish, English and German without any difficulties, but I write it myself fluently. The Futhark of 16 kinds is worthless to write however (or rather, very difficult to decipher, because there are not enough runic translator online to make the many sounds necessary), so don't spend time there.

Furthermore, the younger Futhark has no supernatural use for which Elder Futhark was created (if you do this, look up Uthark's interpretation, for example, "Night Sides of the Runes" or Atrid Grimson's "Shamanism Runmagi och."
