Stranded. I had to cut away about half of the bare wire to get it to  
fit into the PCB holes, and I probably weakened some of the wire I  
left when cutting some away with the stripper. However, when the  
power cable flexes, the flexing happens solely at the point where the  
power cables meet the PCB since that's the wire's most flexible point  
being that there's no insulation there.

I guess I don't completely understand how this would work. Wouldn't  
the wire still have its weakest and most flexible point right where  
the wire joined the pin and thus be prone to breaking there? Maybe  
I'm missing something obvious in my newbie ness.

Thanks for your patience and your kind assistance.
