Haven't had a chance to use it yet but my new Battle Board just arrived. (https://battleboard.us/) It may be a bit small to be a good kit for the Rebelle Rally (http://rebellerally.com). Our maps are huge for the rally. We do fold them down to be more manageable from the co-pilot's seat. Having all your pens, rulers, scales, and maps in one spot is a huge bonus. Losing any of your tools can be a disaster. I'm looking forward to testing this kit out and report it here when I'm done. So far, very impressed with what they have created.
