Don't knock it unless you've tried it.
I'd bet Garry Goodman's strings would make it up to A4 at that scale.
Yeah, I know Garry's strings can get up there, but iirc at those lengths people have had a heck of a time getting them to tune up without breaking. My thinking was that a 27" would work well for F# to A, and 30" would work better for C# to E. But yeah, I haven't tried it, and I've never tried an O4P string, so I'm going on heresay. You've got lots of ERG experience, though, so what are your thoughts? Is this a good scale length for C#1 or A4? Or maybe it's good because it's kind of in between, allowing experimentation at both lengths? I'm personally basing most of my comments on all the conversations we've been having about Tom Drinkwater's 10 strings and their scale length options.
