I'm fine to agree to disagree, but I'm not sure you understood my meaning of shift.
The string vibration has nothing to do with it, I'm talking about the pulling/pushing action of a pick or fingers, do it to hard and the saddle moves. While you can be sure the saddles cant move under normal circumstances for you, you cant for other people. It has happened to me a couple of times. It could have been down to playing style etc, but on the last note of a song, I like to emphasize that note so could hit it a bit harder. I don't like having a bridge sitting there telling me I cant do that, or it will slide about. This cant happen on either the BA or Gotoh, and is actually believe it or not why they have those features.
Ah, okay, you mean the saddle deflects when you pluck the string. I guess I could see that, maybe, although it seems like you'd have to be playing unusually hard.
