well, i'm loving these strings. they seem to have the perfect balance of tension, so they're not floppy; and softness, so they don't kill you to play them. what i'm finding is they sound best, for me, when don't dig in too hard, so gigs are less fatiguing ... no prob with the amplifed sound in a number of contexts, although i'm still tweaking that some. and the acoustic sound is so sweet. the only concern is a general lack of energy on upper register notes past thumb pos ... but i don't spend alot of time there, for what we do.
i'm sure all the comments from everyone here are valid for what folks are looking for in sound, feel, etc for their particular bass, but for my little (little?) upton hybrid, they rock.
