The InTouch RIO Grand is a full line size heavier than the industry standard, and features more weight distributed towards the front of the line to easily load faster action fly rods - making it the best choice of line for fast action fly rods, or for more novice casters that like a little extra load to help them with the cast.
The InTouch RIO Gold has a taper design that gives incredible loop stability at distance and a front taper that delivers perfect presentation of flies between sizes #2 and #22.
