Got a Bibler I tent last year for a lightweight mountain tent. Love the tent, but the poles that came with it just don't hold up. While searching for options I came across a website that will make poles for a variety of different tents. I ordered a set to replace the original aluminum ones. The factory ones weight 15 OZs and the replacement CF ones weigh 7 OZs. Nice way to drop 1/2 lb, especially when I needed new ones anyway.
