Nope, my take is that the string doesn't ever stay up the bridge pin to the point that it isn't touching the bridge top -- ever, unless the net bearing is so negative that it's trying to pull the bridge off of the soundboard. Bridge expansion pushes the string up, and the string follows the bridge top back down when it recedes. The pin stays in the bridge simply because it is tightest in the bottom of the hole, where it's under nearly no stress at all. Ron N
