I used to use Warwick red labels on everything because they are so cheap you can change strings every week. I love nothing better than fresh steel strings. I tend to say you can always dial highs out but if the strings are old, dead or done you can't dial anything in anymore. But I noticed a significant degradation on the red labels that occured with time. I had quiet a lot ..well how is that called in English..? The string core was broken on numerous new set of strings. It hit me once on a weekend in the studio when 5 out of 10 sets had dead e strings right out of the packing. I had to fight in the shop for getting them replaced and again 2 of 5 sets were like that. Even more bad was that suddenly I had problems to get my basses ..oh god...my english... in German it is called octave purity? What it means is that you can play an octave anywhere on the bass on any frets and it is "in tune" and sounds fine. I gave two of my basses to my tec guy and was afraid their necks had gone twisted but it turned out that with any other strings than the Warwicks tuning was just fine. Only with the red labels the problems occured.
So I changed to D'addario Steels. Double the price of the Warwicks but I think they last a bit longer and they have more bottom.
