Although this is a very old thread, I'm glad it got revived as it's an interesting topic. I also do lots of hiking with my camera. Foolishly I used my Manfrotto monopod for dual purposes, and it broke on me after only two years of "light" use. I then realized that one shouldn't use just any monopod as a hiking stick no matter how good it may be for photography. When I then started searching for a replacement for the dual duty monopod/stick, one of the things I also wanted to add was a self-defensive feature/weapon, simply because I have ran into wild animals more than once and I'd feel a whole lot better about having something to protect myself and my family with -- just in case (little protection is better than nothing!). The answer was the Gitzo GM-3550 Mountaineer 6X Carbon Fiber Monopod with stainless steel spike at the tip. Initially I purchased a short spike, but I'm thinking about getting one that is 4.7" long. The combo is pricey, but the technology behind the monopod is unequaled and will last a life time.
