It's always the I Formation - Twins. They call the load option that goes to the side with the TE, away from the WRs. If I'm in man, there's no one in the flat. If I'm in zone, he can go the other way and have two WRs block down on the CB and then go to the next level and get the S. The QB either darts up the A gap, or if they crash down, he simply runs parallel to the line and dives upfield. It's not like I never stop it, but I have a lot of trouble and would just like a consistent way to contain it when I know it's coming.
