You could always skip the rod and just bring the tackle to save weight and an extremely awkward shape. Haha. I started off with a rod that I carried around in a PVC pipe, then graduated to a collapsable rod, then to a "pocket fishing kit," and, finally, currently fish for bluegill, trout, and catfish using two pieces of foraged wood. One piece of wood I shave smooth and use as the spool. The other piece of wood is about 3 feet long, shaped like a Y, and serves as my casting rod. I wrap the line around the spool, "point" the spool where I'm "aiming" my cast, and zing the slip-bobber away using the Y-stick casting rod.
There are a couple drawbacks, of course. Admittedly, I have never caught a trout this way, but I have heard that others have had trout-success with this method. I have caught a bazillion bluegill/perch/bream and catfish using this method. Also, if you weren't using a slip-bobber, and instead fishing with any kind of leader line, casting would become more difficult.
To me, the drawbacks are worth it not to have to carry around a pole. All of my tackle fits perfectly into a USGI PDK box. And as for those brookies and brownies, I do so love a great challenge. I mean, that's why we fish in the first place, isn't it? :thumb:
