Well, to be honest... it was many years i didn't use rotosounds on my bass... so i put those strings on my trustee fender jazz standard. Well, they have an hard tension (which could be fine for some styles, but not for me). The tone is warm, but a little dark (again, could be fine for some styles...).
Anyway, the tuning is stable and they're lifetime is very long, after one month of hard use they still do the job.
