MUT challenges 100% complete

So I was just wondering if anyone in the community has completed 100% of the ultimate team challenges yet. If so what challenges did you enjoy most?

I myself am almost done with the zero chill group of challenges needing only 15 more OOP challenges to be 100% so far the 12th day of MUTmass was the hardest for me, but finally got the 1st play big run with Adrian Peterson on a toss play run.
