If all you need is the roadbook and an ICO then I think the RMS sytem will work fine. I used it during a three day draining last year and had no problems, didn't really notice the weight on the bars at all. I also think this system is probably a little more crash worthy as it can rotate. For Dakar there is so much more needed to be mounted that a fix mount on the steering stem makes sense. I'd keep it as simple as possible.
