We're all used to the 4 wall v 4 wall, at the Jammer line, starts. What would happen if the front team swung round 90 degrees and lined up own the middle of the track.
Your Jammer lets the other pick a side, then goes the other way. You wait until the Opposing Jammer has committed then sweep sideways. Your Jammer goes up against 2 or 3 opponents, their Jammer goes up against 4 of you and 1 or 2 trapped team-mates. Enough to give you that extra advantage you need to get lead.
