I just don't see how another several steps up to 1/0 or 2/0 would make any further difference. (But I'll be driving through Portland this afternoon and if halekai36 spent $130 on everything I may be sold - that sounds like a great price no matter what the gauge for every cable and lug in the bank and to the starter and back!)
Don't forget you'll need your own battery lug crimper or Dave will make them on the spot if you have your measurements. Knowing your lug sizes (bolt hole diameter) ahead of time also helps..
He's also the best price I've found anywhere on heat shrink terminals 10-22 ga.
