Which set-up would be more ideal for less heat and more runtime:
Set-up A:
-4s 6000mah
-higher kv motor
-gearing to match battery and motor set-up
Set-up B:
-6s 4000mah
-lower kv motor
-gearing to match battery and motor set-up
I also read that with more voltage, there would be more cogging; hard to start off or run at slow speeds. Is this true?

Who said that? That's not been my experience at all....It would seem more dependent on the esc programming more than anything.
The only complication I've seen w/ this is that w/ high turn motors you can run alot lower FDR. Every ESC has limits to how slow it can run the motor, say ~120rpm, so that min spd is higher w/ a low FDR.
Other than that the setup is very smooth. It would be too much for racing only if you choose too hot a motor, but this is true of any system. If you run a 2000kv motor on 6S, you will be flying off the track. Just choose the motor for the final desired spds and you are good.
Also, the battery choices you have have exactly the same amt of energy, so runtime won't be greatly improved, but will be a bit better w/ B as you are losing less to heat.
