I agree with that as well. They were rough to the point of almost feeling sticky. The Hi Beams don't feel like that, although these SIT nickels are even slicker.
The only gripe I have about the stainless ones is that when I play with a pick (a medium pointed V-pick) I get a distinct metallic tone that is not particularly pleasing. At least the DR strings aren't as expensive as the aforementioned Thomastik flats. Of course, one set of those will outlast the bass itself.
