Wow -- Gus, did you really carve those sticks? They're beautiful!
It is interesting how different kinds of woods perform differently. I don't care for metal sticks. Mr.P uses a metal TRAX (I think it is called) but my favorite is a plain hazelwood walking-stick that I bought in Scotland for a pound. I brought it home on the airplane (Despite Gautam saying they'd never let me board.)
Wooden walking sticks have more give and flexibility. A stick as tall as a point halfway between your shoulder & your elbow is perfect for me. It is also important for me that the shaft not be too big as my hands are small. They're super when crossing a stream, or testing snowbanks and how muddy the trail is, as well as helping you get up and down hills.
I also have a great stick that came from a watershoot on a Thundercloud plum tree that we left way too long. I thought it would be brittle, but it's going strong after five years. Mr.P cut it to size, and that's all that has ever been done to it. It is a little tall for hiking -- just a few inches shorter than I am, but it's very handy when walking around the pasture and good at keeping the dogs & horse in line, too. A stick like that becomes an extension of your reach.
That one is straight with a slight curve at the very top so it has a nice rake to it.
I started as Jespah did, just finding something along the side of the trail, but sometimes a good stick is hard to find. I have used cross-country ski poles when back-packing, and if I were carrying a big pack, I might consider them again, but I prefer having one hand free. Hope you find the perfect stick for your trip!
