The InTouch Big Nasty is designed specifically to cast large and heavy flies with exceptional ease. The line features a short, powerful front taper that has no problem casting weighted streamer and large terrestrial patterns, and is heavier than the industry standard to load modern rods quickly. The line is built on RIO's ultra-low stretch ConnectCore for the minimum of stretch and the maximum in performance, and features RIO's XS and AgentX technologies, as well as welded loops on both ends. Our ultra-cool, glow-in-the dark LumaLux version is perfect for throwing Hex patterns at night, and for casting games!

CONNECTCORE

When you rely on touch to know what’s going on in the depths, line stretch is the enemy.

Our ConnectCore lines open up new worlds of perception and sensitivity with ultra-low stretch performance. Soft, subtle takes become positive grabs, and without stretch to dull reaction times, hook sets are instant and sure. ConnectCore. The secret weapon for success.

AGENTX

Traditional, single-layer fly lines have to compromise between function and the need for durability and slickness. AgentX Technology makes the old compromise obsolete by bonding two separate coating layers onto one line.

This proprietary process allows RIO line designers to optimize the specific performance of each line. For example, AgentX floating lines can use an inner layer with more buoyant microspheres, while the outer layer is formulated for maximum toughness and shooting ability. AgentX means the best of both worlds in a single fly line.

EXTREME SLICKNESS

Every fly fisherman is looking for a slicker line, and for good reason. Slicker line means longer casts, which is something all anglers strive to achieve. XS Technology is the latest development from RIO's lab coats that focuses on creating an ultra slick line, with dirt-repelling tendencies.

XS (Extreme Slickness) Technology began when RIO's chemists began reformulating conventional chemical combinations. Although RIO's formulas were great, our scientists are fly fishers, and by definition they want an even slicker fly line - it's just part of the deal. So first, they tackled the polyvinyl chloride (PVC) coating and through intense scrutiny down to the polymeric mix level, (say that 10 times fast) they defined some fundamental limitations. Out went the old PVC/silicone formulas and by methodically adding a little more of this, a little less of that, and a pinch of secret sauce, the lab coats cooked up a completely new and improved recipe. With XS Technology, RIO has developed a fly line that is slicker, more stable, and far less apt to attract dirt, and paired with AgentX Technology, it engineers a line that is less dense, casts further and more accurately, floats higher, lasts longer, and offers more consistent performance cast after cast, strike after strike, fish after fish.
