I keep running across wire rope terminations that have been made with 4 crimps instead of 3. I am well aware that 3 crimps is what is prescribed for nicopress copper sleeves but loos and co. say 4 crimps for their sleeves. Is there any difference between loos and co. sleeves and nicopress sleeves that would explain this? They appear identical to the naked eye. I am probably going to replace the pick lines that have 4 crimps just because I can and I have anecdotal evidence that the crimps were made with a cheapo Chinese swager. Just curious what other rigger's opinions on the subject are.
