Hernan holding tuna caught while fishing Opsin leader
ā˜…ā˜…ā˜…ā˜…ā˜…
ā€œI’m newer to fishing and have tried lots of flouro during my tuna and rockfish trips. Opsin has been my favorite line to run by far! It ties strong knots, stays organized in your tackle box, and best of all it gets bit even when the tuna are line shy! Flylined 25 and 35 lb test line and ended with more fish on deck than anyone else.ā€
