If you are fishing where you need to get deep to reach big fish this is the line. The head portion of the line is 30 feet of Type 6 sink tip. It will easily get you down 10, 20, 30+ feet deep. Plus it casts like a dream. 

From Us:
We love the Outbound Short for fishing off the beach for kings or silvers, or in larger rivers where dropping your fly through heavy current is mandatory. This line is the best out there for turning over big flies and when you let it go it really flies! Plus the ultra-low stretch in the line makes for solid hook ups. 

Exceptionally powerful, easy casting, line built for maximum distance, with ultra-low stretch performance.

The Outbound Short is a 100 foot line. The running line is 70 feet of intermediate sink and the head is 30 feet of Type 6 (6.0 ips) sink tip. 

From Rio:
RIO’s InTouch OutBound Short series of lines are designed to cast large and heavy flies very long distances. Built with RIO’s ultra-low stretch ConnectCore Technology. A short, aggressive front taper easily carries large, weighted streamers, while the powerful head design loads rods deeply and efficiently for effortless casts. A full range of densities make this a very versatile line series. Each line features RIO’s XS Technology for super slick performance, and is built with a supple, coldwater coating that ensures the line remains tangle-free.
