I have been fishing and backpacking for a good part of my life. Lucky for me I live in California, so i can fish the sierras in the summer and the delta in the winter. I to have used a "cane" pole. Really anything will do. I think those Tenkara are cool but I believe its a wast of money. Just use your fly pole with out your reel, thats basically what your buying. Garage sales are great or for a well priced rode try TFO.
Back to the "cane" fishing. In the sierras we (my grandpa and I) would just find any old tree limb or branch. I use the float line then a 3-5 foot leader line, any fly will do. I tend to just take caddies and a winged dry fly along with a wet fly, like a stone fly. Now if you are on the small steam where i fish you can get away with this. Larger rivers will probably be a little tougher. Anyway thats my two cents.
