Proper use of old style hand crimpers

That's a very good question!! I like to use the method used in the first pic because it traps the two ends of the connector. It you do it like in the 3rd pic it tends to open up the open ends of the connector. But I always go one step further and re-crimp with a heavy duty set of crimpers, I can post pics later. These heavy duty crimpers don't have the wire stripper holes, they are only for crimping. Once I've used the crimper that you show in your pics I then crush the connector with the heavy duty crimpers totally trapping the wire.
I'm sure other FABO members will have plenty of input!!!
