With its' long, fine front taper, the ultraslick Rio Premier Rio Technical Trout WF Fly Line excels at delicate presentations of dry flies, nymphs, soft hackles, and emergers to finicky fish. A long head and back taper increase loop control when carrying long lengths, and when laying down precise short-range presentations to rising fish. Optimal weight distribution makes it easy to turn over long leaders. A supple core and coldwater coating keeps it casting true in cold conditions. SlickCast, RIO's proprietary coating technology, creates one of the slickest, most durable fly lines available. Lab tests prove lines with SlickCast exhibit the least amount of friction ever measured in a fly line. MaxFloat Tip Technology, a proprietary tip coating formula, keeps the line floating more than twice as high as regular line tips, without any increase in diameter. Dualtone coloration marks the sweet spot of the fly line with an easy-to-see color change for improved casting. Quickly and easily identify each line using the EasyID printed-line marking system. A smooth, bulletproof loop welded at the front and back of the fly line ensures fast rigging to leaders and backing.
