as soon as the luthier has installed them I will be able to give my opinion

Perfect except for a sound a bit too metallic. It was a test, not disappointed though.

whaouu, compared to the strings I had before on my bass!! A much crisper sound, more present, more sustain, more presence... Well, it's an investment for sure, but according to the comments on durability, it's worth it!!

Excellent strings

Bought in November... Still on my bass... :) I just bought a new set, I'm sharing my impressions on the ones I'm going to throw away: Bright sound (maybe a bit too much at the start), then after 6-7 hours of playing it's perfect ;). After 5 months, the sound started to become "flat" like 20€ strings after 1 month. A fast-fret once a week and hop, it lasts another 3 months easily. I'm changing them to switch to another gauge, but in terms of price/lifespan it's the best, although I've tested quite a few (dadario, fender, EB slinky, EB coated, Elexir long-lasting with coating that peels off...). They'll remain my favorites ;).
