No, but more than flats.

I would argue with this, strongly. Halfwounds sing like nothing else on my basses. I don't get the rounds on fretless thing. They are rough to the touch with lots of finger noise and, as experienced, damage the fingerboard. Halfwounds are smooth to the touch with much less finger noise and loads of mwah.
It all depends on the setup and the way you play the bass. If you dig in you'll loose all the voicing and it ends up just sounding like a fretted bass with dull strings. Play more gently and the sound swells after you pluck the note. Add into that some easy side to side rolling of the left hand finger and you get the most beautiful vibrato. Pulling the string across the fingerboard looses all that sensitivity.
Try halfwounds before you go any further. Get them from the Status Graphite site. Just about the best value strings out there.
