Nice to see the rolls of solder and minimal amount of crimp connectors. I am of the camp to always solder and never use crimp connectors. I know many installers say the opposite, they claim solder cracks. I have never had a solder connection fail, but have seen crimp connections fail. Worse thing of crimp connection is when contact is made, but not with ample amount of the wire, so it tests good but adds resistance to the circuit.
Guns brought up the point... I didn't because I didn't want everyone to think I am a solder snob. I am though. Don't have or own a single crimp connector. They break wires when they cut in, corrode if able over time and cause general problems.
One weller soldering gun 100/140 watt from Home Depot for $30 is all a man needs to solder nearly anything. (yes..I have soldered a pcb with one in the past.)
