Marc Beaumont as well don't ride with his blackbox boxxer during the off season...Saw this on the Fox photo shoot video. I think the DLC coating forks needs lot more maintenance so they just ride the normal forks during the off-season...
I actually noticed that about Marc too. Ya I checked out Greg's fork one day and the DLC looks like it rubs off super easy. Like the first 100mm of his Boxxer was more silver than black.
