When the fish can tell me from his lips that he isn't going to eat an artificial lure that is not real already because it has a snap in front of it then I will start to direct tie. But until then snap on, snap off. We use the spro hyper snap on all of our light tackle and have never had one fail yet.
I use the bigger spro barrel swivels on my heavier stuff, but I have to say that if you open the snap too far it will break right in half. So they are strong if you can get them on the lure with out breaking them, But I prefer the breakaway on the bigger stuff!!!
