87yj,

The IMU vs. dual-RTK situation is a hot-button for me right now.  A firmware update went bad on one of my NVS-NV08C-RTK-A receivers.  It's now in "console mode" which NVS refuses to support.  So it's bricked.

The Tersus is delayed so I ordered a couple Piksi Multis and a couple more IMU Brick V2s.  I'm hoping to migrate to them over the next week so that I can start planting.

I'm not sure what you mean by "driving the direction you are going" but I use the NV08C heading.

My issue now is that I wander around +/- 10cm from the line.  There are a few things I still need to tweak but I'm hoping an IMU will help me stabilize.

I also bought some A/D converters for the Pi.  I'm thinking about controlling steering (and everything else) directly from the Pi instead of going through rosserial to an Arduino.  It should cut down on latency a bit and simplify the system.
