I assume this is for 27 and you are grabbing the second tube by flipping your arm around (hence the RS775 needs to running most of the time). Have you considered trying 987's 2 tube path starting at the Y with periodic line checks. It is the most consistent and creative 2 tube auto I have seen. The periodic line checks & encoders give them all the field reference they need.

We use a whole bunch of sensors (ultrasonics, light, etc) for positioning on some of our single tube auto modes. But for our double tube only uses gyro and encoder because we don't have time (1 sec to spare) to check/adjust for the others. It is my understanding that most of the 2 tube teams (33, 1114, 148, etc) use only gyro & encoder.

Good luck with that double uber auto!
