As suggested earlier to someone who didn't beleive me, and as Scott just pointed out...REAL PIANO WIRE is the best way to go! Unless it is sold as piano wire, it is substandard to our use, if the life of our planes depends on it.Period.The metalurgy is poor in the K&S stuff(It is NOT the same wire we use to get!), and I dont know what McMaster &Carr is handling these days;buy some and TEST it....go with what you know, Gil!
