We are using 2 BB RS550s, Cim-Sim, 26:17 chain increase driving 2 8 in. wheels. We can easily shoot from the top of the key, and even sink the bottom basket while on the bridge.
The 550s easily have enough shaft to engage the pinions. The key is to mount them with a set screw or Loctite 609 retaining compound (or similar product), or both.
