I set up my poncho-tarp today by running the guylines through the straps. It's quick and easy.
I teach cross country skiing. Every year I tell folks how to use their straps to push themselves and most of them are thankful for the tip.
Btw: If your straps are too loose, you'll end up with your hand on the wrong part of the grip. For XC skiing, I have my straps technically too tight, so I can put my thumb on the top of the grip for more push. I have Leki hiking poles with a nice broad flat top on the grip which I use when going downhill rather than lengthening the poles for short stretches.
