Trekking Poles or hiking sticks? I say both.
When backpacking with a 40 Lb pack I do not trust a trekking pole - it may collapse or break. For this I go with a good maple staff. I even drilled out the top and glued in a bolt for a camera monopod.
When day hiking, especially fairly technical stuff I take a trekking pole - just one. I find when I am descending jumping from rock to rock I get tired of concentrating with two.
Both my backpack and daypack have a piece of Velcro stitched up high on one of the straps. The "fuzzy" Velco is glued to the back of my GPS. Add a string for a safety and I am set for receiving a great signal every time.
Happy hiking. Peter
