For me, the Total handles a wider variety of conditions than the Vapor, and I can stay with it longer as the lanes transition. However, when I get the Vapor on the right condition, there's nothing better in the bag in terms of pin carry.
One thing I've noticed about both balls is that they tend to break down a lane *really* quickly, more so than the balls with the regular Activator or PowrKoil 18 covers.
