Strings don't roll at a contact point where the wire has been bent around the point to beyond the plastic deformation limit of the wire. It's a permanent bend. A twist in a string, however slight or severe, would not affect this. >2. String curvature memory from having once been coiled which is visible >in string removed after 30 years of being at pitch. This could have >different affects depending on how this curvature is oriented. People with more experience and better equipment than I have intentionally tried to verify this bit of mythology. They couldn't detect a difference any more than I have been able to with my own experiments. Anything that critical should be pretty obvious to anyone who has ever replaced a string. Since it isn't obvious, I presume it isn't critical. >My experience with our D was a definite perceptible improvement in >sustain, power, and clarity to some notes from taping once >judiciously/gently down on every bridge pin in the killer octave.

Yes, I expect it did sound cleaner. Ron N
