I VOTE FOR POSE... But really i think its anyones game regardless of who is involved in the challenge.
What would be interesting to see is that they weren't judged on the skill level of writing their own names. But rather have the judges throw out a random word at the start of the event and have them freestyle off of that word. Everybody knows they can rock there name properly with style. I think it would have to force them to think more and would probably be more challenging for the contestants. It is a challenge right?
