When I make replacements for tuners who break these strings high up in the scale all the tuner wants and all I want is strings that won't break and that are as close as possible to the originals, which in this case is not very close. If somebody really wants the strings properly designed and safe, then they can order a whole set. Neither I nor my customers are going to lose any sleep over a lousy little Yamaha upright. All Yamaha strings are bad. >Can you describe the formula you use for what you refer to as the yield point? I simply go by the figures I was given over 25 years ago by the wire manufacturers for the maximum strain and the 70% of that is what experience has taught me and other stringmakers. My strings don't break and many of the thousands of odd replacements I've made for tuners who've broken strings we designed to exceed 70%. I've written so much on the list on this question over the years that I'm not going to churn it all out again. I noticed a couple of years ago that Stephen Paulello uses almost identical figures for his "modern" wire to those I have always used and says more or less the same as I say.
