Help: I need high tensile strength strings

[z0z0]

I have a special project instrument which has a scale of 24.75" and I want a string that will hit A (440Hz) open.

For a 0.009 string I need 22.02 pounds tension to hit the note but that is 86.5% of the "average" tensile break point of 25.45 lbs for a string with 400k PSI UTS (if I am using these terms properly).

If I find a string with a tensile strength of 450k then I get down to 76% of the break point tension.

Does Earnie Ball have any high tensile strength strings?

I guess I am SOL with EB as their average tensile strength is just a bit above the mean and so will not meet my needs.

Interesting project??
