A lot of teams have problems getting a reliable crimp on these much larger wires. If you go the crimp route, make sure you have an adequately sized tool and whoever does it has the strength to use it correctly.
Also, the Anderson connectors are well made but sometimes the contacts get a little charred or the crimp comes loose. Take a look at the contacts and give the wires a wiggle to verify they are clean and tight.

You are correct adding another 5' of wire only adds another .002 ohms of resistance when using 6a wire. In other words not enough to have a noticeable affect on performance.
