24 pin atx connector pin removal (sleeving)

Hello, I've been sleeving my cables with Paracord and have come to a stop because the 24 pin MOBO connector pins simply refuse to come out.
I've successfully sleeved my CPU, GPU and SATA power cables with no problem so I think my technique is correct. I don't want to pull the wires too hard for fear of the cable breaking, leaving the pin left in the connector.
So my question is: Are the pins in the 24 pin connector always more resistant than others?
Otherwise I can always cut the cables and resolder them, but I'd preferably do the usual way.

Thanks in advance.
