dicey, and not recommended. 2-8 lb rods are more of a noodle than a rod... if you set the drag correctly and are highly skilled in playing the fish, it might work. but a 7 footer is a little short for controlling your line when bobber fishing - can be done, if you're on higher ground that would help.
your main concern is if you hook into a freight train pissed off winter nate, you'll get spooled in no time. a noodle cannot turn or stop a freight train.
