Not a good day for wires

I went to swap the boots on the cables today and had gotten through most of them when I managed to pull off the crimped connector that's inside the boot from 2 of them. Looking at the wire, its not hard to see why. I'm sure pulling on all of the boots stressed all the wires and the jacketing of the wire is very soft. The crimp pulled right off. Needless to say, I have a new set of wires on the way along with a note to the vender complaining about the quality of these Mag Wires. It totally ruined my day. It will be interesting to see if the new wires make a difference to the misfiring problem. I sure hope so. I'm running out of ideas.
