Choosing the best line for topwater fishing can be a difficult proposition. There are several ways you can go, and each one of them has its benefits and drawbacks. The old standby is monofilament. I like Sunline Defier mono, usually in 17 or 19 pound test. Mono floats, it does not backlash badly, and it’s easier to cast, especially when you’re in a hurry. The drawback to mono when fishing topwater is the extra stretch and it can be more difficult working your bait from a long way away. The other way you can go is with braided line. I prefer Sunline SX1 35 on 50 pound test. I also use 65 pound test when throwing a frog. Braid has no stretch, and it can be easier to work the bait, and it’s often easier to extract fish from hang ups with braid. The drawback to braid is castability – it’s just not as easy to cast, especially when casting in a big hurry like on schooling fish. The other thing you can do is to put a monofilament leader on braid. This is an option I use quite often when throwing a prop bait, a popper or a walking bait. It is probably my overall favorite way to fish topwater. My leader length is 7-8 feet and I end up retying the leader knot about once a day. The bottom line on fishing line is that it’s really personal preference. You just have to get out there and decide which one you like the best.
