RIO's Technical Euro Nymph Line comes with an integrated leader and has a mono core for ultimate sensitivity and stiffness.
RIO Technical Euro Nymphing Line is ultra thin and ultra light for the utmost sensitivity for quick hook sets. It's a level line that can be cut and tuned to individual preferences. ( no back end loop )
The best feature and a brilliant design feature of the Technical Euro Nymphing line is the integrated leader. The core of the line extends past the front end of the line ( think airflo poly leader) and becomes a leader, resulting in no knots to get caught in the guides. The leader is .013 in diameter, pink and level so it to can be cut to desired length. All one needs to do with this line is add a tippet ring to the end of the pink integrated leader and some tippet and you are euro nymphing, easy peezy. Overall length is 94ft, 80 of that is the fly line.
