May 30, 2011 at 2:50 comment added user6976 Probably even the depth in the lower central series would be a lower bound. But isn't the depth linear in length? As I understand a similar problem exists for Heegard splittings. What is the lower bound there?
May 30, 2011 at 1:42 comment added Ian Agol I think you can get a lower bound on the length from below in terms of the depth in the derived series, but I expect this is far from a sharp lower bound.
