I was looking forward to trying these strings given how highly rated they are, and ended up being extremely disappointed.
I tried them on a hollow body semi-acoustic, didn't plug them to an amp yet, just tried them unplugged.
EADGB strings are not bad, a bit bright but I like it well enough.
The treble e string is horrible though, way too bright and metallic, strumming sounds horrible (and this is compared to the old strings I've had for years). The e string is very prominent and loud, very ear piercing.
A nylon pick mitigates this somehow but I still don't like it and would never buy them again.
I hope the Optiweb version is better.
EDIT: the strings mellowed a bit and I got used to them so I edited my rating.
I would probably not buy them again though, and will go for pure nickel strings next time
