I would go for atleast 14ga. This is btw the size most manufacturers use. Novak is 1 of the exceptions since they use 12ga for their race esc's.
Basicly the thinking is, the bigger the wire, less voltage drop per inch. You do have to take in to account the weight of the wire, thats why no1 goes over 12ga.

True, though you may not realize that even Novak is using more 14AWG wire now. All GT7's come from the factory prewired with 14AWG wire now(it actually took me a bit by surprise, because I'd been used to using 12AWG so I had to be a bit more careful in soldering on the Power Pole connectors that I use)....

Default Wire Size?

It's true that 14 gauge wire is easier to work with and is sufficient for most applications. I was told by Novak tech support that the reason for using 14 gauge on their GT7 ESC is for more convenience to the consumer (easier soldering and more flexibility). However, larger wire size will give you more current flow (when needed) and less resistance. This would probably be noticeable in high current applications such as drag racing or sled pulling, but for average 6 cell applications the gains would be minimal at best. The most important thing when deciding on wire size is to keep solder joints to a minimum and use high quality connectors or even hard wire if applicable.
