Use the designated line weight for your rod. The line is overweighted by .75 sizes, so compatibility depends on rod specifications.



Eric Sutherland –
Used this line for bonefish and permit in the Keys. The clear tip helped the fly stay hidden and reached fish that were otherwise wary. The sink rate is consistent and the line holds up well in saltwater.
Dorothy Berry –
Great for targeting tarpon in shallow waters. The intermediate tip gets the fly down quickly and the line feels solid under pressure. A bit heavier than expected, but works well with my rod setup.
Mary James –
Felt like a game-changer for my saltwater fly fishing. The clear tip is visible in the water and helps with fish detection. Tropi-Core stays smooth even in warm, humid conditions.
