I would highly recommend 2 poles. While hiking on the AT, they hardly ever get in the way. There are very few ladders/cliffs where it is better to use your hands. Moreover, I am no doctor, but I can imagine walking 2000+ miles with an uneven gait can do some serious damage to your body. Walking the AT with an even gait can do serious damage to your body, but I think less so. Most polls have straps around the wrist. It is easy to climb, swat, investigate, etc by just letting the poll hang. I hiked from Katahdin to Gorham, NH without polls. I fell every day, suffered a pretty serious ankle turn, and could hardly deal with the pressure on my knees. I picked up a pair of polls in Gorham, and barely stopped the rest of the way. The benefits were magnificent. I did wipe out at the Pen Mar line, but only because I’m an idiot. Who put that chain there any way?
