I've been playing guitar for almost 30 years now

my main thing is fingerstyle guitar in the style of players like Bert Jansch, Davy Graham and other British 'folk, blues and beyond' style players as well as a healthy smattering of MS John Hurt, Rev Gary Davis and other fingerstyle country blues guitarists.
Anyway... for years I've slumped up the the counter and just bought whatever strings with no thought outside of gauge. Part of it is I really don't like getting treated like a heel by some 'salesperson' who's trying to upsell me or making me feel like a thief by hanging over me. I just want to browse... the clerks bottomless knowledge of what guitar strings the guy in Creed uses matters less than a hill of farts to me. I'm not a rocker, I'm not a folk strummer, I don't care what those guys do, it just doesn't apply.
Back to the point, when I try new fiddle strings I really do my homework. I have a few go to brands but to stray from my big 3 takes a lot of research and first hand experimentation. One time, for kicks, I tried some round wound fiddle strings, they were horrid - by far the most unmusical things ever. Which made me think "If I use round-wounds and they sound like a cat's-ass and flat-wounds sound good on my fiddle. Why not use flat-wounds on the guitar?"
I had looked around at flat-wound sets a while ago and all I could find was nickel-wound electric guitar sets (seemed to be aimed at Jazz guitarists) I just assumed they didn't make flat-wound strings for acoustic guitars.Then I found Pyramids, they at least don't say electric guitar on their packaging and it seems like some reviewers use them on their acoustic guitars.
I've also heard Pyramids are darker in tone than most strings. FWIW I play my guitar strings until they fall off because I don't like the sound of new strings, I know some people who love the brassy sound of a new set - but I actually *don't* like that sound. I also wish I had less 'fret-noise' especially when playing slow airs and other pieces.
So anyway at $25 a set are they worth it? Any first hand experience with them? How do they hold up to DADGAD and other alternate tunings?
