RE: 10S x 1 or 5S x 2?
I was thinking that too, Adam. I thinik one nice thing in getting the 5s packs is that you can use them in other stuff. If I ever get around to it, I have a .30 sized electric heli that uses 5s packs. I also plan on getting a .40-.60 sized e plane to use the 5s packs in.
On the plus side, you would probably have a litte lighter battery because you would be minus two connectors and wires.
