I know you are not interested in a new rod right now but you might start reading about Tenkara fishing. While I still prefer a western style rod and reel, Tenkara rods fit well with ultralight backpacking (particularly for small streams) because no reel is involved - just a rod, a bit of line and tippet, and a few flies. The rods are about 18" collapsed and very light weight. The whole outfit runs about 3 to 4 oz and under $200.
