Yours for a mere $99 (and probably £99 in UK) Rio's latest product video sent out today -
"RIO's new top-of-the-line InTouch Technical Trout fly line is made on an ultra-low stretch ConnectCore that provides incredible levels of sensitivity when casting and fishing.The line features a long, fine front taper for the lightest of presentations, and easily turns over the long leaders typically used when targeting technical feeders." Yada yada yada
Obviously my other lines are now destined for tying up runner beans.
Thank goodness for Mr Barrio!
