BacpacJac,
Jolt's idea is a great one, but put one of the poles on each side of the waist, not behind the back. I expect this is what Jolt meant, but when I first tried it years ago, I tried it with a single pole. It is a PAIN, literally. This way the poles won't poke you on the downhills and when you stop.
Respectfully,
Jerry
Yes, that is correct. Sorry for the incomplete explanation. Also, crossing the poles is recommended for better control.
