Google Shopping shows the PA2067 MMJ die available at 3 online stores. Digi-Key lists it too. What are the pros and cons of the die and a PA8000 CrimpALL, versus the IEC tool ( https://iec.net/product/modular-crimp-tool-for-rj11-dec-mmj-connectors/) ? If one either already has an RJ45 crimp tool; or doesn't have any crimping tool at all?
