I've never been a fan of poles; they seem like extra weight to me, especially now that I'm using an ultralight hiking style. But... I'm planning a section hike on the AT next year and everyone seems to recommend them. Can you tell me the pros and cons of using (and carrying!) poles on the AT? (I plan on hiking from Springer to Fontana Dam next May). Is there a brand to really consider? Is there a brand to avoid? What price range should I be looking at? Should I ever bother?

Thanks,
Tejloro
