If I had to pick one, definitely Whole Lot of Leavin'. Lost Highway works pretty well at the beginning of a show, and Sleep is somewhat well known. I personally think BWC works better live than Born to Follow, just because it has one of the best sing-along choruses of any song released in the 2000s and 2010s. We Got it Going On works well live, but is a terrible song overall, and should be permanently replaced with One Wild Night.
