i've been trying a full set of solo Dominants recently, tuned down to orch pitch.
the solos tuned down sound and feel great, not too floppy, but you'll need a good "scoop" under your E string, unless you just love that rattle, some folks do.
lots of sound, good sustain with a natural sounding decay, just about perfect, b/c they bow well too. they come pretty close to the sound i've been wanting to peg, McBride's tone on "Love Scenes" by Diana Krall. dark but not stuffy, gritty but not zingy, on my bass, at least.
i just switched off from Animas, and of course that's one amazing string, so the fact that i'm this happy with the solo Doms i think says a lot for them. they amp more clearly for me, which is more important to my work.
