Richard, I suppose it could be the wire, based on the fact that it's only the 14g wire that's fussy. Are there other notes of 14g that aren't problematic, or no? Could just be a fussy section of the piano. Is there humidity control on the piano? What's the environment been like there? I know it's only the one section, but sometimes all those other common suspects can make an otherwise tolerable problem much more, er, problematic. One trick I like to use is squeezing the wire just in front of the hitch pin to stabilize that bend more quickly - not overdoing it, but basically aiming to get the wire coming around the pin tightly and off the pin straight. I don't know that it's your solution, but it might help. William R.
