Not Really a fly line at all this line is designed to have as little drag on the water as possible and slip through the guides with ease. I cut mine in half so I can add it to my normal fly line like a tip. That way if you want to fish an indo or the hatch starts popping off you can remove the line and re rig with max efficiency. You get 2 lines for the price of one this way too RIO's updated Euro Nymph line has been thoroughly vetted and approved by FIPS Mouche as Competition Legal.
