Catalpa are much better than any larva I’ve ever used. You have much lower chance on losing bait on a missed strike, a pretty big deal when trying to really trying to load up on catfish for a big fry. While I’ve caught maybe 50 fish in the 25-50lb range the only 2 over that were 2 that went 70lb and 72lb. Both using single Catalpa worms on Pickwick lake and on noodle left over night in the rivers main channel.
Just my 2 cents.
