You stated that these 2 rods are rods you acquired which leads me to believe that they were used rods which you have no info on. I think you would get a more accurate answer from someone here if you would tell us what is written on the rods and the brand names because the one you state is a larger diameter and heavier may be an older fiberglass rod and the other one you stated was a sleek lighter rod and it could possibly be a graphite rod, but, until you tell us what brand of rods these are, it would be difficult to answer your question. There is a world of difference between the action of a fiberglass rod and a graphite rod.
Just a thought.....

Fly fishing and fly tying are two things that I do, and when I am doing them, they are the only 2 things I think about. They clear my mind.
