Carolyn Harris –
Used this line on a flatwater trip in Queensland. Caught a permit and a bonefish within the same day. The clear tip helped with fish detection and the 8-foot sink tip worked well in shallow waters.
Owen Gill –
Good for beginners and experienced anglers alike. The clear tip makes it easier to see fish in murky water. A reliable choice for flats fishing.
Jacob Davidson –
Fished with this line during a tarpon season. The intermediate sink tip allowed for better control and reduced spooking. Highly recommended for warm water flats.
