Back in the dark ages !
I believe that I was taught that all things being equal, that stranded wire would carry more current than solid wire ? Is that true or am I being misled ?

More wires give more surfaces for current to travel on. Finer the strands the greater number of surfaces. Considering the same size of wires.
Current does not travel on the wire surface until the frequency gets to about 20 KHz. It is not an issue for power.
Well, no skin effect exists for ALL frequencies above 0 Hz. (DC). It's just that for it to be noticeable for many conductor sizes it needs to be pretty high frequency. However, Power companies need to deal with skin effect even at 60Hz. given the size of conductors they use.
