Ollie:
Sorry to hear about the Optima's. I bought three sets for my Alembic, but haven't tried 'em yet. I figured that even if they were sheisse, they'd look great for photo ops as my bass is dripping in gold, LOL! I figured if they were good enough for John, and they didn't prematurely wear-out my frets, that they were worth a shot. And yes, they were $50 a shot on EBAY! They're not, to my knowledge, available Stateside any longer.
Oops, my bad.
Anybody out there in Alembicland wanna buy unused Optima 45's in GOOOOOOOOOLD, LOL!
FWIW, my luthier won't string anything with S/S strings unless the instrument is originally equipped, or refretted, with S/S fret wire. He says the ridiculous fret wear is not worth the slightly brighter-for-longer tone. Just change 'em more often was his response when I asked (i.e., nickel roundwounds on everything, even on jazz boxes, and he's an accomplished gifted jazzer!)
