If we're allowed both a field guide and a binder, I think the teams that succeed at this will be the ones that can correctly balance the use of both resources. If you lean too heavily on one over the other, I don't think you'll do as well. One of the most difficult things would be finding the right information to put in the binder, so as to have as much information as possible, but not so much that finding the right fact is hard.
