which would draw more amps?

First off, spinning a feigao that high isn't that good of an idea. They like to run around 35K, so 67K is a bit much.

If you are running the same voltage and getting both motors to do the same amount of work, the amp draw will be the same. If you went with 6S on the neu, and regeared accordingly, that combination would have a lower amp draw, because of the higher voltage. The watts output (assuming you are going for the same speed) would be the same as the 5S, since again, you are doing the same amount of work.
