WHAT SIZE CABLE DID YOU GUYS USE?

I found some 2Ga american made welding cable tonight for $2.09 a foot. I was thinking about picking up about 10' of for a ground wire. I wasn't sure if I should use a heavier gauge wire for the positive cable from the battery in the trunk to the starter or not. What do you guys think?
