Gavin Murray –
Used this line on a trip to the Great Barrier Reef targeting giant trevally. The 65lb Tropi-core held up well under heavy pulls and the sinking head helped place flies accurately in deeper water. The AST Plus additive made the line slide smoothly through the water, which improved casting performance.

Felt more durable than other sink tip lines I’ve used. The floating running line worked well with the sinking head for better control in variable depths. A solid choice for saltwater big game fishing.

Perfect for targeting tarpon in deeper flats. The line loaded quickly and maintained strength even during long casting sessions. The added slickness helped with consistent casting and reduced line tangles.
