Objective: How can I straighten bent gutters?

Which of the following solutions is more sound in terms of naive physics reasoning?

Pick from: * To straighten the spikes without removing both them and the gutters, use a 2-ft. length of angle iron and a heavy metal chain link with the center section cut out of one side. Working from a ladder (be careful!), you'll find that the angle iron and chain link provide easy leverage to straighten out the spike and get the gutters back in alignment. * To straighten the spikes without removing both them and the gutters, use a 1 inch length of angle iron and a heavy metal chain link with the center section cut out of one side. Working from a ladder (be careful!), you'll find that the angle iron and chain link provide easy leverage to straighten out the spike and get the gutters back in alignment.
