If there is one fly you should have in your box, then this is it!. A true seatrout classic and it still catches a lot of fish every day. It's a bit of a fly that can be anything, nothing specific, but it works well... all year long. And the most beautiful thing is: these kinds of flies you can cast all day without getting tangled. One of my most beautiful catches was a first cast in an early morning at very shallow waters...This fly!
