Tough call between the 2......
- B.Gill as the HARDEST puller. Their broad body digs in.
- Smallmouth for FUNNEST. It can be amazing when you get hold of a jumper. Wading in the river and having them jump out of the water to (or above) your eye level is a sight.
One other odd-ball FW species that puts up an amazing fight for its size is a River Redhorse. They love to run and take a long time to tire out. Shaped like little torpedos. A decent size one on light tackle or fly is a challenge.
