And yes I considered the possible over-volting of the the LEDs. After a couple sleepless nights, I came up with the idea to combine cable sizes to control the voltage drop. Like I said, the drop was so borderline that even resistance from the number of connections could affect it. We'll see what happens when I do the project.
"borderline", you answered your own question. Put down the 10ga and do it right, why risk it. Sleep well at night.
