well i have two fishing rods that are medium action and call from 6-17lb test line on them. they are both about three years old but have never failed me. One is a Rhino rod and reel, and the other is a PX(Army post exchange) brand. i bought power pro 50lb test and thinking of spooling them up. will there be any downfalls to this? Or should everything operate the same as it has been?
