Linc, I typically just use needle-nose pliers to bend the crimp wings down so that they hold the wire while I solder it. That way, IF you need to remove the wire, you can just heat it up and pull it out since the crimp isn't holding it in.

I would say that a well-crimped connection will have no discernable difference in resistance compared to soldering. However, if you think about it, if you start with a crimped connection, and solder it, the soldering fills in the gaps between the round wires in the crimp. So that should have less resistance. No?
