Sorry, my point was just that when you lower the stop-bar you increase string tension. Your neck will move forward so the "sounding" part of the string will be shorter and not intonate well. When you bring the neck back to your favourite, some, at times most of that will go away but to get it right, you still have to listen and adjust... I think, it ll comes down to the neck boring more or LEDs stressed. If anyone's got another idea, I be glad to hear of it.
