Crimps were the standard in the computer industry when I/O had 3/4hp motors, pumps, pulleys and gears in them. We never had problems with the factory crimp. It was field crimping that caused problems, mostly because the wrong tool was used. We did have the right crimpers available but they were not always as handy as they could be. I would solder and shrinkwrap (or tape) a questionable splice because I hate "call backs".
