I believe that a great deal of A314s practical success is due to the self-effects, and I apply it to my neck. The mindset, the awareness and the drive are it’s best features, IMO. I like it best when combined with P75 (in males,) causing a vocal pitch drop, (lets your voice relax, I think) - though I suspect there is some p75 in it already.
Thegentlemen notes that he felt angry when combining the two, though.
