I've been backpacking for about 2 years now and I have never needed trekking poles. I'm young and in good shape so I never saw the point in bringing them, until a combination of a lot of running and hiking has started to take a toll on one of my knees. For that reason, I'm going to start using them next year and I need to invest in a good pair of poles. However, I have no idea where to start. I've heard some bad stories about Black Diamond's customer service so I'd probably like to start with Leki, but they have so many different options that I don't know what to choose. Weight and price are a factor, but I'm not willing to drop a significant amount of money just to save a few ounces. What do you use? What would you recommend? Thanks guys!
