The 30 amp powerlines are simple to crimp 12 to 14awg wire. For 10 awg you need the 45 amp. Or destrand it to 12awg thickness.
The 45 amp powerlines are difficult to crimp properly without their special tool.
I went years crimping 8awg Into the 45s before acquiring the special anderson crimptool.
I bought some dies for flag terminals and insulated terminals. Which fit into the anderson crimpers making them multipurpose. I also remove the little plastic anderson spoon contact holder and crimp non insulated terminals with the anderson dies.
The 30 amp contacts are very easy to assemble without the special crimper if one has a dimple crimper But the special C likely does a much better physical and electrical connection.
If you are near NCSD coastal. I can make up your cables if you bring the 45 amp powerpoles.
