Hi Dale There is a new other way to improve those tenor zone. The problem is the low breaking point about 35% for note # 21 of a S&S B French piano maker Stephen Paulello come with the genius idea to make string with softer steel. With this note # 21 F you will have about the same tension and a better breaking point of about 55% with the Paulello String model O and the possibility to change the scale to have less tension but normal BP...!! There is two other model 1 and 2 for older romantic piano like old Erard or Broadwood Paulello offer a free Excel program all you need is to put the speaking lenght and choice the best type of string to got the breaking point you looking for each unisons. I just use those string this week on a 85 notes S&S B in the low tenor, great result...
