On the practice field before elims, we were able to balance 3 long base robots. 869 has their battery on a track, which allows them to shift weight. Buzz Team 175 has one heavy end, with a brake, to allow them to hang half their robot off the bridge.
We (team 126) have tossed around the idea of using our bridge manipulator as a "stinger", or designing something before going to STL.
