I understand what your saying, but i oriented my solder connections to the board in a certain way to relieve stress when it is assembled, had i turned the output wires around, they would have crossed the swith and been turned at a sharp angle, placing more mechanical strain on the solder joint.
Same goes for the battery to board joints, they allowed me to loop them over and connect to the bullet connectors on the battery and be tucked down beside the battery in the box.
I see your point on using the 16g from the battery and 14g on the output side. But it is what it is now.
As for the switch wires, they are more than clear of any other components and are not really a concern.
When I planned my wiring, i took into consideration the stress placed on the solder joints more than anything, so I avoided any tight bends in the wire, and made sure there was a plan for every wire placement.
