The type of wire you use can also make a difference. I use wire that has a high number of strands and comes pre-tinned. The number 12AWG has 60 strands for example. Assembling and wiring various equipment for the aerospace industry (back when it existed) we called this type of conductor switchboard wire. I think the designation is SISX wire.
