Team 40 used Andy's Servo shifters last year and a vex 7.2 battery for a backup battery. They worked great, though I would recommend servo savers as we broke about 8 servo's using them. The gears in the servo kept breaking so we just bought replacement gear sets. We used a shift on the fly as a turbo button so the robot ran in low unless "turbo" was pressed and the shift was instantaneous. We didn't cut power to shift which may also have had a negative effect on the servos.
