Hello Alpha Bears welcome to the forum. I like your idea of tent pole convert to fishing pole. Pretty neat one.

I do agree with Glenn however, it is a bit risky to be messing around with tent poles in the event that they break you are out of luck.

Just another thought to go along....Lay the pole between two trees to create a clothesline and have yourself a place to dry some clothes.
