I'm actually drifting back to IDC. Now that I have a pneumatic IDC tool I can make up a cable in seconds. I was all wanting to get what I thought were better results with trifurcon crimps etc, but really, the assembly is a complete ball ache (yes, using proper crimp dies and all) and I'm over it. I actually haven't had a new IDC fail yet so I'm going that way pretty much all the time. Power leads probably the exception. Good solid crimp and housing there probably still a good idea.

I think that's because of the different plastic allowing a different amount of give in the friction lock.
