I’ve used this line for bonefish and permit fishing in the Keys. The AST PLUS additive makes a noticeable difference in how far I can cast and how well it handles wind. The head is strong and responsive, and it doesn’t fray easily even after multiple casts.

Great for tarpon fishing in the Gulf. The line performs well in choppy conditions and stays intact during long casts. I appreciate the added durability and the smooth shooting action.

This is the first fly line I’ve tried with the AST PLUS technology. It shoots farther than my previous line and feels more consistent when casting in the wind. Highly recommend for saltwater fly fishing.
