I will be climbing Mt. Rainier in June and wil be bringing along my Canon 20D and 18-85 IS lens. I need to bring along a tripod also, but my Manfrotto/Bogen tripod and ball head are way too heavy. So, I'd like to buy a new lightweight tripod for the trip. Obviously, I could go with the very expensive carbon fiber tripods, but I really don't want to spend more than a couple of hundred dollars. I would be grateful for any suggestions. I hope to be taking landscape shots as well as candids of our adventure and I will need to have a tripod. The trip will require me to carry about 40 pounds before I add the weight for the camera equipment, so every ounce counts. Thanks in advance. Shane.
