If I were to prepend the network 1.1.1.0 to come in on 'sprint 1', but have a route to 2.2.2.0 via 'sprint 2' so that traffic comes in on one circuit but returns on the other, routing is broken. If I change my route so that packets directed to 2.2.2.0 return on the same circuit that the traffic is received on, everything works fine.
