About this strings, i don't know if i say thatthey are good or if they are bad. I tried it on regular basses like fender, squier, others than warwick and this strings never sound good, on fingers it seems like pure steel, it seems like "glue" to our fingers. Of course that this aspect it's equal to every basses, i mean, the physic aspect. But on sound it works good on a warwick bass, it sounds better than rotosound on warwick bass, and that it's why i don't know if i talk good or bad about this item. My recomendation is: If u have an WW, buy this strings because it works very good. If u are not a player from WW don't buy it, because it works very badly.
