What are they for? Is there something I've missed in 35 years of backpacking without them?

I swore I wouldn't use them and they are rarely essential, but fooling around off trail with a backpack camp + boned out mulie I'm glad to have them. Improved balance is the primary benefit for me. I also carried them on a 33 hour 56 mile blitz in the Bob Marshall and they came in handy to take some pressure of of the feet near the end. One is good enough for some trips, and sometimes I leave them behind. My GG Lightrek 3's weigh 3.0 oz. per pole, so taking one along is a small weight penalty.
