I am not a fan. I've bought a few sets over the last 10 years or so, just to come back to them and give em another go, but everytime I'm disappointed by the inconsistency. Seems they have a tendency to feel, sound, and look different from string to string. Same experience with their flatwound guitar strings. Maybe they've gone downhill since their glory days in the past?
That said, this is kind of the same issue I have with TI flatwounds, though TI and RS have a fundamentally different formula. The RS strings are definitely on the higher tension side.
