Recently, Jesse Johnson has used paths in the pants and dual curve complexes of Heegaard surfaces for a 3-manifold M to define invariants of M. We adapt this approach, employing the pants and dual curve complexes of bridge surfaces for a knot K in a 3-manifold M to define invariants of (M,K). We will discuss several easy calculations of these invariants and also talk about some interesting associations between distance in the pants complex and hyperbolic geometry.
