If I were to prepend the network to come in on 'sprint 1', but have a route to 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 return on the same circuit that the traffic is received on, everything works fine.

You might be running into uRPF (unicast reverse path forward verification).

Strict-mode uRPF will couse this, I am sure sprint support can help you with it..
