Hello,
Bacon has done a workshop at the championship event focused on branding and marketing for the past two years. We have video and an accompanying slide show accessible through our Facebook page here:

We have guidelines when dealing with our image and our marketing materials, and we have carried that through our promotional materials. (found at

I would agree with a set of guidelines for using your logo. It's apart of your team brand and should be as consistent as possible
