Karl, if you go onto Stephen Paulello's website, you will find the treble wire scalings for a number of different pianos, such as all the Steinway models. He lists two types of scaling, normal and intense use (meaning concert). For example, a Steinway D will have the last 31 notes using XM instead of M. That is gauges 13 1/2 through 16. In this example, he does not change the gauge, only the wire type.
I believe that Bosendorfers are scaled at higher tensions than Steinway. At any rate, you will want to get the speaking lengths and wire size for the plain wire, so that the scale can be analyzed for breaking percentage and properly targeted adjustments can be made for the substitution.
Like Jim, my use of XM has been limited to the upper treble, when the original scale breaking percentages are too high. In this case, it not only solves potential problems, but it also sounds and blends better with the notes below.

Type XM has a higher BP% than the other wires, and higher than Roslau. I use it in the high treble only, but gauges 18 -13 are available.

Never say never Mr. Sutton.
In a related question; Is there one species of Paulello which is good for replacing oft breaking Roslau? I remember reading somewhere that he had developed something like this. I have a Bosendorfer 280 which absent a new bridge placement needs a different type of wire for octaves 5 and 6.

Well, I just have a small shop now, for actions and hobbies, but this piano was looking for a home and there was room in my office....

Will and Jim-
Thank you for your encouragement.
The piano is a 1972 Kawai No. 550-C, 5'10". It will be my little swan song piano, so I'd like to hear what Paulello wire can do.
I'll do the entire piano with Paulello wire, and have Heller make the bass strings.
