Reading your post, I began to think of the reasons why there is so little comment on A314.
Is part of it just because A314 works so well? (I’m thinking of that Showtime Rotisserie infomercial where they keep repeating the mantra “Just set it and forget it!”) I normally use one drop where chest meets neck after I dry off from my shower, spread around with a glass rod. After that, there’s nothing else to do …
I haven’t found anything that doesn’t work as expected with A314 – no surprises.
