Cable question for pro's


We had been using security cable from WCW for a pretty long time because it came off the box well, has different color stripes and it has the pull string in it. However, we are really unhappy with the last couple of orders. They must have a new supplier because they pull out of the box really poorly. The rep says I'm the only one to complain about this but that is what I would expect them to say.
I am looking for a new source for cable. My biggest hurdle which is proving to be difficult, is that we want cable with the pull string in it. None of the local suppliers carry it anymore. I am surprised to learn that other pro's don't want the string. If you use cable with the string, where do you get it?
