Second best defense for 2-ball auto is the portcullis if you have a mechanism that lets you reverse through it. Or since you need a pickup on your back side to do this, probably a mechanism on your front side as well as on the pickup. After that your percentages probably drop by a lot since you're likely being randomized by the defense or the landing afterwards.
