Just to add to the debate over solder vs crimp, in the marine and space industry crimps are the preferred choice, LLoyds insurance, who write the book on how to do marine stuff, only like crimps. solder is well known failure point due to vibratiion. Also the problem of the solder being a higher resistance joint, which in extreme circumstances overheats and melts the solder out. If you want to see vibration, check out out a satellite launch, all crimp connections.
As you say though, your call.
BTW I am talking about good quality calibrated crimp tools and quality crimps.
Poor quality crimp tools are a complete gamble, and I don't like to gamble with burning peoples boats or vehicles.
